A qualified constant temperature and humidity test box is not only some important accessories for imported brands, the technical indicators meet the requirements, or meet the relevant standards. Rather, care about the details, as small as the casters, observation windows, lighting and other small parts must be perfect. For example: standard type constant temperature and humidity test chambers are all equipped with observation windows to clearly see the test conditions in the laboratory. During the operation of the equipment, if the observation window is not selected properly, it will cause fogging on the observation window and cannot clearly see the test status in the laboratory. And the inferior observation window is also easy to break. In summary, the observation window should meet the following requirements:
The observation window of the constant temperature and humidity test chamber should adopt a funnel shape design, and the observation field of view is wider. The material is double-layer hollow tempered glass, which has the advantages of high temperature resistance and low temperature resistance. And the observation window glass is equipped with a 15V conductive film constant temperature, this design embodies the advantages especially at low temperatures. When the test chamber is at a low temperature, the surface of the observation window will not be very cold due to the low temperature in the laboratory. The observation window will not frost and the laboratory will not be clear. To see the situation in the test chamber more clearly, it is also necessary to equip a lighting lamp, and the lighting system uses the Philips kit.
