    • product
      The OGS-335F4 is a dual channels thermopile device having an output signal voltage directly proportional to the incident infrared (IR) radiation power. Two infrared narrow band pass filters in front of the sensor provide methane (CH4) gas absorption signal and reference signal simultaneously. 
    • Thermistor temperature reference included
    • High sensitivity
    • Fast response time 
    • Narrow band pass filters
