Constant Temperature Humidity Chamber - Stability Test Chamber - -5 to 70°C - 15-95% RH

The Master Science Temperature Humidity Chamber holds samples at controlled temperature from -5 to 70 °C and humidity from 15 to 95 % RH for long-term stability testing of pharmaceuticals and quality checks of food, tobacco and cosmetics. It is also used for ageing and water absorption tests on paints and resins and for reliability testing of electronics, automotive parts and metals.

A frost-free refrigeration design avoids the drift and swings that defrost cycles cause, so conditions stay steady over long studies. Six sizes run from 103 to 1022 litres.
