HM-T96 Humidity Monitor

HM-T96 Humidity Monitor

The Apex Instruments HM-T96 Humidity Monitor is designed to protect gas analyzers by monitoring the relative humidity of the sample between the sample pump and flow panel.


The module will alert you of undesirable conditions before the dew point is reached and will shut down the sample pump to protect the analyzers.
We’ve also equipped this humidity monitor with a fail-safe electro-optical switch for detecting condensate, located in a stainless-steel coalescing filter assembly.

The HM-T96 uses a Relative Humidity and Temperature Sensor equipped with an Optical Condensate Sensor, which is designed for use in harsh environments.
