Touch screen high and low temperature test
Introduction of constant temperature and humidity test box:
Constant temperature and humidity test box, also known as high and low temperature alternating humidity and heat test machine, is a necessary test equipment in the fields of electrical appliances, aviation, automobiles, home appliances, coatings, scientific research and other fields. It is used to test and determine the resistance of electrical, electronic and other products and materials. Parameters and performance after changes in test temperature and environment such as dry, drought resistance, cold resistance, and humidity resistance.

Touch screen high and low temperature test

Details



Constant temperature and humidity test box features:
◆ Adopt imported high-precision microcomputer color touch screen temperature and humidity controller, switch between Chinese and English,
◆ Test hole (left side of the machine) 50mm, can be used for external test power line or signal line
◆ Original sealed compressors imported from Europe and the United States
◆ Double-layer high-temperature-resistant high-tension sealing strip is used between the door and the cabinet to ensure tightness.
◆ The inner and outer box is made of imported (SUS # 304) stainless steel plate.
◆ The observation window is made of multi-layer hollow tempered glass, and the inside is laminated with a sheet-type conductive film (the test process can be clearly observed)
◆ Safety protection device, when any fault occurs, the fault status is displayed on the screen and the power is cut off to ensure the safety of the machine, the tested product and use.
