Product introduction
Environmental test box can accurately simulate low temperature, high temperature, high temperature, high humidity, low temperature and low humidity and other complex natural environment, suitable for plastic, electronics, food, clothing, vehicles, metals, chemistry, building materials and other industries of product reliability testing.
Step-in constant temperature and humidity test box is suitable for aerospace products, information electronic instruments and meters, materials, electronics, electronic products, various electronic components and gas parts in high and low temperature or humid and hot environment, testing its performance indicators.
Product features
1 The design is perfect
Arc shape and surface spraying treatment, high texture appearance, and the use of flat non- reaction handle, easy to operate, safe and reliable.
2 Large observation window No Hirohiroaryo:
Using three-layer vacuum coating window and Philips energy-saving fluorescent lamp, without wipers to remove fog, maintain a clear observation effect, can observe the status of the test at any time.
3 Separation of water and electricity ensures safety:
The pipeline of the humidification system is separated from the power supply, the controller and the circuit board, so that the leakage of the pipeline can be avoided and the circuit can be affected and the safety can be improved.
4 The refrigeration and control system is advanced and reliable:
Original imported Europe and the United States fully closed compressor, imported environmental refrigerant, world famous brand of refrigeration devices, imported LCD touch screen controller, friendly interface, easy to learn.
