It is very small and lightweight and suitable for on-site measurement.

Since it is aerated in a closed container, it can measure even low concentrations with high sensitivity.

Calibration (standard solution) is not required during measurement

The sample collection volume is as small as 10 or 50 mL.

There is no need for temperature compensation, and measurement variations among operators have been reduced.

Almost unaffected by coexisting substances in the sample.

The cleaning filter is not affected by ambient gas.

Dissolved ozone, trichlorethylene, tetrachlorethylene, dissolved sulfide, and ammonia can be measured simply by changing the detector tube.
