HM-T96 Humidity Monitor

HM-T96 Humidity Monitor

The Apex Humidity Monitor is designed for monitoring the relative humidity of the sample between the sample pump and flow panel to protect gas analyzers.


The module will alert you of dangerous levels before the dew point is reached and will shut down the sample pump to protect the analyzers. There’s also a redundant electro-optical switch for detecting condensate located in a stainless-steel coalescing filter assembly.

The HM-T96 uses a Telaire T9602 Humidity and Temperature Sensor, which is designed for harsh environments.
