OEM PID Sensor module
... ensuring most reliable performance in VOC monitoring
Model SCU OEM-PID2
The model SCU OEM-PID2 , VOC Sensor Control
Unit (SCU) PID module, is an OEM module for the detection of volatile organic compounds, with an ionisation potential < 10.6 eV. With its built-in electronics and micro-controller, as well as a combined humidity / temperature sensor, it provides
a flexible and easy-to-use adaption into your customized VOC measurement.
It has all the built-in signal linearization, with temperature and humidity compensation. You do not have to worry about signal not responsive or not repeatable. It has been all taken cared of.
