Description for Humidity chamber

The HCP climate chamber is used for testing at high temperatures and humidity for wear resistance, storage time under critical conditions, packaging strength, resistance of metals and alloys to rust. The device is equipped with six-sided heating to prevent water condensation and a steam generator with constant water replenishment. Humidity in the chamber is regulated with an accuracy of 0.5%.

The Memmert HCP240 humidity chamber has a capacity of 8.5 Cu Ft (241 L) with a temperature range of 6° to 90°C and comes with dual digital display controllers with programmaning. This climate chamber offers the full range of comfort, reliability, and safety. It has active humidity control set from 20% to 95% rh and an unsurpassed homogeneity of temperature and humidity over the entire interior. It is suited for environmental testing, environmental simulation, accelerated service life tests, and 85/85 tests according to IEC 60068-2-67 and IEC 60068-2-78.
