Laboratory high and low temperature test chamberSuitable for the testing of finished products or components such as electrical, electronic products, aerospace products, automotive parts, various electronic components, plastics, LED lamps, etc. in various stages of production and inspection, providing a constant humid and hot, complex high and low temperature alternating test environment and test conditions, testing the heat resistance, cold resistance, dry resistance, and moisture resistance performance indicators of various materials.
Especially suitable for fiber optics LCD、 Crystals, inductors PCB、 High temperature resistance, low temperature resistance, and moisture resistance cycling tests for products such as batteries, computers, and mobile phones.
Laboratory high and low temperature test chamberOperation of the system
It is achieved through three interrelated systems: refrigerant circulation system, air circulation system, and electrical self-control system; In the refrigerant circulation system, the liquid refrigerant in the evaporator absorbs heat from the air (the air is cooled and dehumidified) and begins to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant also evaporates into a gaseous state, which is then sucked in and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After being throttled by an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant that enters the evaporator, completing the refrigerant circulation process.
The high and low temperature test chamber (high and low humidity alternating test chamber | high and low temperature testing machine | high and low temperature alternating humidity test chamber) mainly provides a constant humidity, complex high and low temperature alternating test environment and test conditions for the testing of electronic components, industrial materials, and finished products in various stages of research and development, production, and inspection. It is suitable for various industries such as electronics and electrical appliances, communication, chemical industry, hardware, rubber, toys, etc.

1. Adopting an electronic parallel micro humidification system, equipped with two magnetic spring switches, can reduce errors caused by electronic devices.
2. The humidifier cylinder is made of stainless steel as a whole.
3. Adopt evaporator coil dew point temperature (ADP) laminar contact dehumidification method.
4. Equipped with dual protection devices for overheating and overflow, it can be used with peace of mind.
5. Humidification and dehumidification systems are independent.
6. When supplying humidification cylinder water, pure water or RO reverse osmosis water should be used as much as possible.
