The compound salt spray test chamber is an upgraded version of the touch-screen salt spray test equipment. It has the function of alternating temperature, humidity and heat based on temperature and humidity adjustment. It is used to test various performance indicators and quality management of samples under alternating compound conditions such as high temperature, damp heat, dryness, and salt spray.
This chamber uses a 7-inch high-definition touch LCD, which supports the preset of the test program. The program mode can set salt spray and humidity test at the same time, and the machine can be used to perform common alternating salt spray test, dry and wet compound salt spray test, or independently perform NSS test, AASS test, CASS test, damp heat test, and dry test. The heating and cooling of this machine can be in rate control, and it has the function of correcting the reference point of temperature and humidity. The humidification and dehumidification systems are completely independent. It is equipped with an automatic water replenishment system, which automatically completes replenishment when the water level is too low, and it also can use manual water replenishment. Its time setting range is as long as 999 h 59 m, with a power-off memory function, and it can continue to execute the remaining programs when power is restored.
In order to ensure the cooling rate and minimum temperature requirements of the chamber, this machine adopts a compressor refrigeration system, which includes a compressor, radiator, evaporator and throttling device, etc. The heat exchange is realized through an evaporative condenser.
