Temperature humidity test chamber is used to test various types of materials for their tolerances of heat, cold, dry, humidity. It is applied for quality inspection for all types of electronic products, electric appliance, and products from communication, instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries.
Temperature and humidity testing help to determine the behavior of the components in severe test conditions and environments that involve fluctuatingenvironment, high temperature, and different relative humidity. The tests can be done with constant temperature and humidity in a static state and can bedone in a dynamic state where the moisture is used to induce a failure of the components or materials.
Main Features
1.The constant temperature and humidity test box is mainly composed of control panel, distribution panel, insulation layer, air supply fan, heater, humidifier and refrigeration unit. The main specifications can be divided into 6 standard sizes and 10 specifications under different conditions.
2.The controller can be connected to the computer through LAN interface. Users can design programs on the computer screen, collect test data and records, call program execution, remote control machine switch and other functions.
3.The use of multi-wing air supply fan strong air circulation, to avoid any dead angle, so that indoor temperature and humidity distribution is uniform.
4.Complete safety protection device, if abnormal conditions occur, the controller screen will automatically display the fault status, cut off the power switch, and provide troubleshooting methods.
