Manufacturer of Constant Temperature and Humidity Test Chamber/Constant Temperature and Humidity Test ChamberSpecially test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. This machine can choose Chinese or English LCD touch screen display, with simple operation, easy program editing, and user-friendly design. It can display complete system operation status related data, execution and program setting curves. If an abnormal situation occurs during operation, the screen will immediately sound an alarm, display the cause of the fault, and provide troubleshooting methods
1.Curved shape and surface spray treatment, high-quality appearance, and use flat non reactive handles for operationConstant temperature and humidity testEasy to make, 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.
