The temperature and humidity test chamber can simulate various temperature and humidity environments and is suitable for testing electronics, automobiles, rubber, plastic glue, metal and other products. It meets the reliability and stable performance parameters of GJB150A3/4 in various harsh environments. Will provide you with a basis for predicting and improving product quality and reliability.
The shell of the constant temperature and humidity testing equipment is made of high-quality A3 steel plate with plastic spray treatment on the surface. It has an arc design and smooth and natural lines. The inner tank is made of SUS304 high-quality stainless steel plate, which can constantly control the test temperature difference of ±2℃. The indoor sample racks and other accessories are made of SUS304 stainless steel. The insulation material of the equipment pair is: high-density fiberglass wool, and a transparent window is set on the door to observe changes in the indoor sample.
The observation window is made of multi-layer hollow tempered glass.
The humidity adopts stainless steel boiler steam humidification method, high-precision PT100 humidifying cloth sensor, fast response and accurate control. The mixing system uses
long-axis fan motor to make the temperature and humidity in the laboratory uniform and stable. A double-layer high-temperature-resistant high-tensile sealing strip is used between the door and the box.
The test hole (on the left side of the machine) can be used to connect external test power lines or signal lines (the hole diameter or number of holes can be based on customer instructions) ). High-quality, fixable PU movable wheels are installed at the bottom of the machine, making it easy to move the machine to a designated location and finally fix the casters.
Control system
Constant temperature and humidity test equipment generally uses the "TEMI300" LCD programmable temperature controller imported from South Korea or the "OYO" imported from Japan
Temperature and humidity Control instrument and temperature and humidity comparison table, intelligent high-precision digital display PID microcomputer temperature control instrument, membrane button, touch setting, digital and direct display, humidity direct display percentage, temperature sensor Use PT100 platinum resistance tester. The temperature control adopts thermal balance temperature adjustment method. The "TEMI300" liquid crystal display programmable temperature controller imported from South Korea can be used for program testing. It can have multiple groups and multiple stages
programming operations, optional fixed values ??and programs, and the function of setting the time arbitrarily. The temperature and humidity comparison table displays the temperature directly, the humidity refers to the temperature and humidity pair
parameter settings, and the temperature is compared to the humidity. The main electrical components of the equipment, such as circuit breakers, AC contactors, and small relays, are all made of the "Shi
Nide" brand, and other electrical accessories are made of well-known domestic brands.
Heating and humidification system
Heating uses far-infrared nickel-chromium alloy high-speed heating electric wire, high-temperature completely independent system, humidity uses stainless steel tube built-in nickel-chromium alloy
High-speed heating electric heating wire and high-temperature magnesium oxide powder, fast response and long life. The heating and humidification systems are completely independent, and the humidity has an automatic water replenishing device.
