Walk In Chamber
Introduction:
Walk in chamber is a kind of climate chamber. The main difference from the ordinary constant temperature and humidity test chamber is that Walk in chamber is suitable for large size or certain special equipment and technical methods to make its indoor temperature and humidity conform to the requirements of a certain humidity control and standard atmosphere for testing. Walk In chamber adopts intelligent control mode to realize the function of refrigerating, humidity test ,hot and cold temperature test, temperature and humidity test of the unit, so as to control the temperature and humidity of the indoor environment accurately. Walk in chamber mainly used in textile testing system, paper detection, metrology calibration, coating testing, packaging testing, precision machining, three coordinate testing, research institutions, etc.
