Photovoltaic constant temperature and humidity test chamber/constant temperature and humidity test chamber WeihuangGenerally, it can be divided into programmable constant temperature and humidity test chambers (touch screen)/Button type and single point constant temperature and humidity test chamber. Used to test the degree to which material structures or composite materials can withstand continuous environments of extremely high and low temperatures, in order to test the chemical changes or physical damage caused by thermal expansion and contraction. Applicable objects include metal, plastic, rubber, and electronics……Waiting for materials can serve as a basis or reference for product improvement
1.Arc shaped and surface spray treated, with a high-quality appearance and a flat non reactive handle, easy to operate, safe and reliable.
2.Adopting three-layer vacuum coated windows and Philips energy-saving fluorescent lampsNo need for wipers to defog,Maintain clear observation effect and be able to observe the condition of the test sample at any time.
3.The separation of the humidification system pipeline from the power supply, controller, and circuit board can avoid the impact of pipeline leakage on the circuit and improve safety.
4.Original imported European and American fully enclosed compressorImported environmentally friendly refrigerants,World renowned brand of refrigeration components.
5.Original Korean imported controller with LCD display in both Chinese and EnglishLCDTouch panel, face-to-face interactive input data, programmable temperature and humidity, front light17Adjustable segment, curve display, set value/Display value curve.
