Description / SE-4 VOC Sensor

The SE-4 module is the pre-calibrated replacement sensor used for the C-21 VOC Monitor. 

The sensor (SE-4) is a serviceable part on the C-21 and it's a good practice to replace it annually.  When the C-21 is no longer responding to gases and vapors, it's likely due to sensor failure and must be replaced.

The C-21 is broadly sensitive to most VOCs, but its response is different for each one.  To calibrate for a specific gas, a chemical laboratory is required.  To view this procedure see Tech Note C-100.

 SE-4 VOC Sensor Replacement:

Sensor replacement on C-21 is simply plug-n-play.  Remove the old SE-4 sensor and replace with the new one.

 Replacing the SE-4 sensor on the C-21 VOC Monitor is simple
