Thanks to a combination of temperature, humidity and digital CO₂ control, the 256C model can also be universally applied for building material tests or for applications in the field of cell biology that require temperatures below room temperature.

The climate chamber covers a temperature range of -10 °C to +60 °C without humidity and from +10 °C to +60 °C with humidity. Active humidification and de-humidification can be set between 10 and 80% rh. The electronic CO₂ control with automatic zero setting (NDIR measuring system) in the ICH 256C ensures an absolutely precise CO₂ atmosphere from 0 to 20 % with an adjustment precision of 0.1 %. CO₂ is introduced via a sterile filter.

The ICH series is completed by the climate chamber ICH 256 for stability tests of pharmaceuticals, as well as the ICH 256L with an illumination unit in accordance with ICH Q1B, option 2.

Already in its third generation, Memmert GmbH develops and manufactures laboratory appliances with more than 150 employees at two locations in Germany. The product range includes devices such as heating oven, incubator, sterilizer, vacuum drying oven, Peltier-cooled incubator, CO₂ incubator, humidity chamber, constant climate chamber, climatic test chamber, temperature test chamber, storage chamber, waterbath and oilbath.

The appliances are used for a very wide range of applications, e.g. material testing, component inspection, biological, chemical and food research, quality testing, human and veterinary medicine.
