ENV-03-3

Low Humidity Test Chamber

Simulate exceptionally dry environments down to 5% RH and -25 degC dew point using desiccant dehumidification.

5 degC to 50 degC 5% to 30% RH Dew point -25 degC

Overview

Purpose & Application

The ENV-03-3 low humidity chamber simulates extremely dry conditions from 5% to 30% relative humidity in the 5-50 degC range. Lower dew point reaches -25 degC. Desiccant-based dehumidification combined with controlled water evaporation gives stable low-RH set points for storage simulation, electronics conditioning and material studies.
