Handheld Odor Meter OMX-ADM is appropriate for detecting pet odor and putrid smell, checking the effect of deodorization before and after cleaning in hospitals and nursing houses.

  • Display odor strength level in numeric values.
  • Display odor intensity which is converted into ammonia concentration.
  • Detect odor in manufacturing and converting factories.
  • Measure pet odor and smell of excrement.
  • Check the effect of deodorization before and after cleaning at hospitals and nursing houses.
  • Measure garbage odor level in garbage disposal plants, restaurants and fish markets.
  • Monitor smell of compost in livestock plants.


Real-time Digital Indication

The numeric odor strength level is displayed continuously.

Odor Intensity(*)

Displayed value is converted into ammonia odor intensity by the scale of 2.5 to 5.0 based on odor concentration of measurement environment.

*Odor Intensity is determined based on Japanese Regulation, which allows to evaluate odor level by 6 scales.


a) OMX takes odor sampling by using inner pump and shows odor strength level.The strength level is calculated by our original formula using two types of gas sensors that responds to different types of gases.

b) OMX detects complex odor and convert it to odor strength level, which means it doesn't classify types of odor.

c) The strength level showed in OMX doesn't correlate with human sense of odor.

d) OMX does not detect odor well if the gas concentration is not high enough for the device.
