Product Specification

Three-electrode? Electrochemical Gas Evaluation Module For FECS-series Sensors EM-FECS(B)??Description:

The EM-FECS(B) evaluation module is designed to perform the testing and evaluation of the three-electrode electrochemical gas sensors in the FECS-series. Since the output voltage (VOUT) corresponding to the sensitivity characteristics can be obtained, the characteristics of the FECS sensor can be easily evaluated.

Three-electrode? Electrochemical Gas Evaluation Module For FECS-series Sensors?EM-FECS(B)?Operation:

The FECS-series sensor is placed into the sensor socket on the EMFECS(B). If target gas is present, the output current generated from the FECS-series sensor(*1)is converted into output voltage. A linear relationship exists between output voltage and target gas concentration.

By measuring in advance the output voltage in a known target gas concentration, that gas concentration can be calculated from the measured output voltage values. (*2)
