Measurement principle
Sensor element

The oxygen in the air absorbs
the electrons on the sensor surface
when it is heated at high temperature.
It becomes a resistance of electrical ﬂowin the sensor element.
If an odor component with a reducing
potential comes to the sensor under thiscondition, the electrons in the sensor canmove freely and the electricity can ﬂow
highly.
This product reads this voltage diﬀerence anddisplays the odor intensity as the measured
value calculated by our original formula.

OxygenmoleculePower supply

ElectronSuction the odor component ...

HeaterOxygen in the air absorbs electrons on the sensor
element surface. The free electrons in the sensor
element goes reduced, and this makes a resistanceof electrical ﬂow.

Odorous substance reacts with oxygen.
Then, electrons in the sensor element can movefreely, and electricity can ﬂow highly.

Odor concentration※ Even in the case of mixed odor, sensitivity characteristics will diﬀer dependingon the target odor. By acquiring calibration curve data for each mixed odor,
simple odor concentration management will be possible with using the odor
sensor. (Calibration curve data acquisition is the charged service separately)

DATE COLLECTSIMPLE THERMO/HYGROMETERZERO POINT CALIBRATION

AA-SIZED BATTERYPOLFA is equipped with date collect faunction
mode. It is possibility that you measure lonk
hours at 1 second, 1 minutes, 30 minutes andso on intervals. Date format is CSV ﬁles and thisis recorded to micro SD card, so you do notneed install any application.

POLFA is equipped simple thermometer and hygrometer

Usually you do not need calibration but you canto support measurement. POLFA is aﬀected fromget a temporary zero point calibration value whentemperature and humidity. After measurement, use thesensor material deteriorate or you need.

Power saving design, up to 16 hours operation
available with four AA dry cell batteries.
Compared to rechargeable batteries, itʼ s easy
to bring spare power supply, and convenientin the ﬁeld.
