Constant temperature and humidity test chamber
It is a necessary testing equipment in the fields of aviation, automobile, home appliances, scientific research and other fields. , used to test and determine the parameters and performance of electrical, electronic and other products and materials after subjecting to high temperature, low temperature, humidity and heat or constant test temperature environment changes.

Highlights of the high-efficiency design of Qiancao humidification
Qiancao humidification method
Humidifier control method: non-contact equal period pulse width modulation, R (solid state relay)
It has automatic water level compensation and water shortage alarm system
Humidity control adopts + R system and same channel coordinated control

Top configuration
Eco-friendly and environmentally friendly
Green science
In order To ensure the cooling rate and minimum temperature requirements of the test chamber, the refrigeration system of this test chamber adopts a cascade refrigeration system composed of imported compressors. This refrigeration system has the advantages of reasonable matching, high reliability, easy use and maintenance
< br/> Strive for excellence and pay attention to details, and use it more attentively
Auxiliary structure
Sealing: A double-layer high-temperature-resistant and high-tensile sealing strip is used between the door and the box to ensure the sealing of the test area
Door handle: The use of non-reaction door handles makes operation easier
Casters: The bottom of the machine adopts high-quality fixed movable wheels
The observation window is made of multi-layer hollow tempered glass, and the inner glued conductive film is heated and defrosted (clear observation Test process)
