３Outline and Features of Odor Sensor POLFA
The odor sensor POLFA is a handy-type monitor that detects odorous substances in gas
by a semiconductor of gas sensor and displays the reaction value as our unique value.
The higher the odor, the higher the value. And the lower the odor, the lower the value.
Therefore, it is possible to compare odor intensity relatively, and it can be used to control
the change of odor intensity and environmental management as well.
Product Outline
Features of this product
★ Excellent performance of the response
A performance of the response is superior compared to conventional products, and
high reproducible measurement is available.
★ Real-time graph display
Displayed graph measurement data in real-time makes you to check the change of
