OEM PID Sensor module

... ensuring most reliable performance in VOC monitoring


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.
