The constant temperature and humidity test chamber is widely used in aviation, aerospace, electronic and electrical products, instruments, materials, components, equipment, etc. for accelerated wet heat testing, alternating wet heat testing, constant wet heat testing, as well as high and low temperature routine testing, cold resistance testing, and low temperature storage, in order to analyze and evaluate the performance and behavior under the specified environmental conditions in the test.

Meet the standards:
GB/T2423.1-2008 Low temperature test methods GB/T2423.2-2008 High temperature test methods GB/T2423.3-2008 Damp Heat Test Method GB/T2423.4-2008 Alternating Damp Heat Test Method				GB/T2423.22-2002 Temperature change test method GJB150.3 Environmental Test Method: High Temperature Test GJB150.4 Environmental Test Method: Low Temperature Test GJB150.9 Environmental Test Method: Damp Heat Test
Product features of constant temperature and humidity test chamber:
1. The outer box of the whole machine is made of SEEC salt coated steel plate and surface spray treated, with a stable and atmospheric appearance 2. The experimental area (inner box) is made of SUS stainless steel plate fully welded and spliced, which is easy to clean, rust free, and clean 3. High and low temperature resistant damp heat insulation layer (thickness 100mm) polyurethane invoice+insulation cotton 4. The temperature and humidity control system adopts a 7-inch programmable touch screen with adjustable values, which has functions such as real-time recording of curves and downloading and copying of data 5. The refrigeration core components are all imported (such as compressors using French Taikang/German Blog/American Grain Wheel) 6. Multiple protection devices (such as fault alarm and cause; fault record; over temperature protection; upper and lower temperature protection; power-off protection; test pause; alarm output; timing function); Refrigeration system: compressor overpressure, compressor motor overheating, compressor overcurrent protection.
