PDEM SeriesHigh-functionality Gas Sensor
Evaluation Modules
- The PDEM series evaluation modules are suitable for evaluation of Figaro semiconductor (MOS) type, electrochemical, catalytic, and optical gas sensors.
- Every evaluation module is factory pre-calibrated using a typical target gas. This allows for monitoring gas concentrations with digital and analog outputs.
- The built-in temperature and humidity sensors can be used for monitoring ambient temperature and humidity, as well as for temperature and humidity compensation of gas sensor responses.
- Compatible with the Renesas Quick-Connect platform
