Love words?An odor American English or odour British English ; see spelling differences is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell.

An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor. While "scent" can refer to pleasant and unpleasant odors, the terms "scent", "aroma", and "fragrance" are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes.

In the United Kingdom and other Commonweath, English-speaking nations, "odour" refers to scents in general—without positive or negative connotations; but in the United States, and for many non-native English speakers around the world, "odor" generally has a negative connotation as a synonym for "stink".

The perception of odors, or sense of smell, is mediated by the olfactory nerve. The olfactory receptor OR cells are neurons present in the olfactory epitheliumwhich is a small patch of tissue at the back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. Each neuron has cilia in direct contact with the air. Odorous molecules bind to receptor proteins extending from cilia and act as a chemical stimulus, initiating electric signals that travel along the olfactory nerve's axons to the brain.

When an electrical signal reaches a threshold, the neuron fires, which sends a signal traveling along the axon to the olfactory bulba part of the limbic system of the brain. Interpretation of the smell begins there, relating the smell to past experiences and in relation to the substance s inhaled. The olfactory bulb acts as a relay station connecting the nose to the olfactory cortex in the brain. Olfactory information is further processed and forwarded to the central nervous system CNSwhich controls emotions and behavior as well as basic thought processes.

Odor sensation usually depends on the concentration number of molecules available to the olfactory receptors. A single odorant is usually recognized by many receptors.

Different odorants are recognized by combinations of receptors. The patterns of neuron signals help to identify the smell. The olfactory system does not interpret a single compound, but instead the whole odorous mix. This does not correspond to the concentration or intensity of any single constituent. Most odors consists of organic compoundsalthough some simple compounds not containing carbon, such as hydrogen sulfide and ammoniaare also odorants.

The perception of an odor effect is a two-step process. First, there is the physiological part. This is the detection of stimuli by receptors in the nose. The stimuli are recognized by the region of the human brain which handles olfaction. Because of this, an objective and analytical measure of odor is impossible. While odor feelings are personal perceptionsindividual reactions are usually related.

They relate to things such as genderage, state of health, and personal history.An instrument that indicates distance traveled by a vehicle. Also called: mileometer. Also spelled hodometer.

The smell of rotten eggs is instantly recognizable, and can be an indicator of a serious problem in your home. In its natural state, natural gas is actually odorless.

Leave the area, call from a safe place, and call your utility company so they can send out a technician as well. The pipes under a shower or sink have a u-shaped trap where water usually blocks sewer gas from leaking back into a home.

To create that barrier, simply pour a cup of water into the bathroom drain. Sources of carbon monoxide in a home can include space heaters, gas, and wood stoves, fireplaces, and untuned car and truck engines.

They work off a variety of technologies. In a biomimetic sensor, a gel changes color when it absorbs carbon dioxide, triggering an alarm. Others use circuit chips or chemical solutions to detect carbon monoxide and trigger an alarm. If your carbon monoxide detector goes off, move everyone outside into the fresh air.

If you can, open your doors and windows before heading outside to vent the gas from your home. Contact a professional to evaluate your heating appliances and any other potential sources of carbon monoxide to prevent a future incident. People with asthma and allergies can find that their symptoms are exacerbated by exposure to mold.

If you do find mold, disinfect non-porous substances like tile with a solution of bleach and water, and let it sit for a few minutes before venting the area. Rodents, raccoons, and squirrels are all prone to getting trapped in neglected parts of a home like the attic or walls.

However, if the smell is a noxious, sickly smell, there is probably an insect nest or a dead animal trapped somewhere in the plumbing or air ducts. Find your local storm guard!

View the whole portfolio.An odometer or odograph [1] [2] is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two electromechanical.

Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometerthe former name especially being prevalent in the United Kingdom and among members of the Commonwealth. Possibly the first evidence for the use of an odometer can be found in the works of the ancient Roman Pliny NH 6.

Both authors list the distances of routes traveled by Alexander the Great r. However, the high accuracy of the bematists's measurements rather indicates the use of a mechanical device. For example, the section between the cities Hecatompylos and Alexandria Areion, which later became a part of the silk roadwas given by Alexander's bematists as English miles long, that is with a deviation of 0.

Since these minor discrepancies can be adequately explained by slight changes in the tracks of roads during the last years, the overall accuracy of the measurements implies that the bematists already must have used a sophisticated device for measuring distances, although there is no direct mention of such a device. An odometer for measuring distance was first described by Vitruvius around 27 and 23 BC, although the actual inventor may have been Archimedes of Syracuse c.

The machine was also used in the time of Roman Emperor Commodus c. For each revolution a pin on the axle engaged a tooth cogwheel thus turning it one complete revolution per mile. This engaged another gear with holes along the circumference, where pebbles calculus were located, that were to drop one by one into a box. The distance traveled would thus be given simply by counting the number of pebbles.

Leonardo da Vinci later tried to build it himself according to the description, but failed. However, in engineer Andre Sleeswyk built his own replica, replacing the square-toothed gear designs of da Vinci with the triangular, pointed teeth found in the Antikythera mechanism.

With this modification, the Vitruvius odometer functioned perfectly. The odometer was also independently invented in ancient China[ citation needed ] possibly by the prolific inventor and early scientist Zhang Heng 78 AD — AD of the Han Dynasty.

Despite its association with Zhang Heng or even the later Ma Jun c. There is speculation that some time in the 1st century BC during the Western Han Dynastythe beating of drums and gongs were mechanically-driven by working automatically off the rotation of the road-wheels. The odometer was used also in subsequent periods of Chinese history. As recorded in the Song Shi of the Song Dynasty ADthe odometer and south-pointing chariot were combined into one wheeled device by engineers of the 9th century, 11th century, and 12th century.

The Sunzi Suanjing Master Sun's Mathematical Manualdated from the 3rd century to 5th century, presented a mathematical problem for students involving the odometer. It involved a given distance between two cities, the small distance needed for one rotation of the carriage's wheel, and the posed question of how many rotations the wheels would have in all if the carriage was to travel between point A and B.

The historical text of the Song Shi ADrecording the people and events of the Chinese Song Dynasty —also mentioned the odometer used in that period.People often ask us how to measure odors objectively and reliably.

This is one of our main expertise and services since Odors are normally quantified by dynamic dilution olfactometric analysis. Olfactometric analysis consists of determining the olfactory perception threshold of a gaseous sample. This does not involve the determination of the quality of the odor. At Odotech laboratories, the olfactometric analyses are carried out with the Odile TMa dynamic dilution olfactometer Figure-1 within 24 to 30 hours of sampling.

Dynamic dilution olfactometry consists of presenting the dilutions of the odourous sample to the jury at a controlled flow using a calibrated olfactometer.


The gas flow is precisely measured and presented to the panelists through sniffing ports Figure In addition to odor concentration measurements, our laboratories can carry out odor intensity measurements, and investigations of odor synergies and hedonic tone. With a significant number of juries certified in compliance with European Standard EN as well as juries that have received preliminary authentication based on ASTM Standard E, we are ready to conduct your analyses in the shortest possible time frame.

For field odor measurements, sampling are carried out on point sources stack, ventssurface sources water bodies, windrow, piles, waste or volume area inside a building. Another option is to use an electronic nose calibrated based on olfactometry measurements.

ASTM International. ASTM E ASTM E reapproved in EN The following services are available: olfactometric analyses with a factor of dilution up to 2, odor concentration measurements as per Standards ENASTM E, CUM, Probit and Logarithmic regression hedonic tone analyses odor intensity analyses juried perception thresholds jury certification as per Standard EN Figure Electronic Nose for onsite continuous odor measurement Curious about electronic nose?

Each model has different gas sensitivity.


Please refer to the table below to choose the suitable model for your application. OMX cannot identify and designate the types of gas. Please note that the devices basically detect compounded gas only. It needs time for warming up to keep sensor sensitivity stable. Please refer to the table below for warming up. To measure odor more accurately, please attach air purifying unit and keep the device on for about 30minutes before use.

There is no correlation between the indicated value by OMX and human sense of smell. Hence it is possible that the OMX may not show the strength value as you expected. This is because the human nose may have a high sensitivity to some low concentrated gases which OMX cannot detect.

On the contrary, OMX may show the strength value even though the human nose cannot detect any odor. This can occur when the OMX detects odorless gas or some other gases which are difficult for human nose to smell. The Handheld Odor Meter OMX is a simplified monitor to check odor strength collectively, it does not need calibration. To make the strength value more accurate, we recommend zero-point adjustment instead of calibration for simplified measurement.

The OMX is not designed to be used for a long time, we recommend no more than ten minutes of continuous use. Please prevent the OMX from directly suctioning cigarette smoke. If cigarette smoke goes into the sensor of OMX, it may cause failure. Please wait until the cigarette smoke completely falls to the floor, then carefully measure the odor so that the sensor does not suck cigarette smoke. If the strength value does not increase during measuring odor, the device interior may be contaminated or some odor factors may be in the device.

Please refer below for checking the condition of air purifying unit:. The OMX is not effected by temperature and humidity changes in normal living environment, however, it may not measure odor properly if there is change in measuring condition such as using the humidifier during the measurement.

We suggest keeping the measuring condition consistent as much as possible. There is no correlation between the indicated value of OMX-SRM and value of human sense of odor intensity, odor concentration or other odor index.

This measurement is based on our original methodology. The OMX-SRM focuses on chemical substances contained in a smell and this device shows the relative strength of a smell numerically by using semiconductor gas sensors. The reading shown on display is calculated from the output from gas sensors using our original measurement to generate a numerical coefficient.
