Climate, Temperature & Humidity Stability

Climate Test
Constant Climate and Climate Change Test

Climate tests are carried out in special climate test chambers and can be conducted under constant climate conditions or simulate climate change.
The climate test chambers can be used, among other things, for testing the resistance of components and test composites, for conditioning materials and specimens or for burn-in procedures for e.g. adhesive composites.

Humidity Chamber

A homogeneous atmosphere and temperature distribution can be set in the humidity chamber. Thus optimal living conditions for organisms such as fungi or bacteria can be generated. It is used for the cultivation of fungi as well as bacteria and testing of material under exposure to microorganisms, but also for the storage and conditioning of components, test specimens or materials under defined conditions.

Technical Data
Temperature range:	from RT + 8 °C
	up to 95 °C with humidity control
	up to160 °C without humidity control
Active humidification & dehumidification control:	20 to 95 % r. H
Number of program steps:	40 ramps from 1 min to 999 h
Interior space (max.):	560 × 480 × 400 mm
Interior space (max.):	108 l
Accessories:	perforated plate / grating

The Picture shows the humidity chamber HCP 108. — Humidity chamber HCP 108

The humidity chamber HCP 108 with test for resistance against fungus (ENV 807) is shown. The camber door is open and a second glass door seals the test chamber. In the test chamber is a glass tank, filled with earth and wood samples. Above the test chamber is the control unit with displays for temperatur, humidity and time. — Humidity chamber HCP 108 with test for resistance against fungus (ENV 807)
