Handheld Odor meter is ideal for Before and After applications, such as air purification and cleaning service.
Real-time sampling mode displays odor change continuously.Memory sampling mode saves data based on the selected sampling rate. (up to 32732 data, 511 files)
Battery operated with 7 hrs continuous usage.
Indicates the relative strength and odor classification numerically by comparing odor gas and purified airDPS(Data Processing Software) allows the user to view data graphically while monitoringFeatures an intake separate to the exhaust port to ensure accurate reading.

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. OMX-SRM indicates relative value by comparing odor gas to purified air. This measurement is based on our original methodology. “Smell” is the information by human sense (sensitivity value), and there is no method that can accurately quantify various kinds of smells. There are some expressions such as “odor intensity” and “odor concentration” which are quantified based on human sense of smell. 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.
OMX-ADM has good sensitivity to ammonia, hydrogen sulfide, methyl mercaptan,it’s used for measuring pet odor and ammonia smell, detecting odor in hospitals and nursing homes, measuring garbage odor level in garbage disposal plants, restaurants and fish markets.
It’s a reference function to show odor intensity of ammonia.
This odor intensity shows human smell in six stages of 0 (odorless) to 5 (intense smell), which is called “6-step odor intensity display method”.
However it’s rough information and there are variations due to individual sense differences.
OMX is converted odor strength value into ammonia concentration to display 2.5 to 5 as odor intensity,it is different from the original odor intensity. It’s just for reference function.
After 3 minutes since the device turned on, it is possible to start measurement by pushing “ENTER” without waiting 10 minutes.
It needs time for warming up to keep sensor sensitivity stable, it is basically necessary to secure the time for 10 minutes for warming up.
There are individual variance of sensitivity.If the same odor is measured with two or more devices, OMX may show the individual variance of sensitivity within a certain range.
However there is repeatability when repeatedly measuring the same odor with one unit.
Therefore we recommend to use the same device for repeated measurements.
