Equipment Introduction

1. Device introduction:

The high, low temperature, and low pressure test chamber is mainly used to inspect and verify the reliability of aviation or military electrical and electronic, instrument and communication equipment and other component samples in various environments such as low pressure, high temperature, low pressure, low temperature, and low pressure. It is mainly used in related fields such as automobiles, aerospace, military, and communication. The equipment can fully simulate the low pressure conventional test under constant temperature state, slope pressure drop test under constant high or low temperature state, and slope temperature drop test under constant low pressure state as required by GBT2423/IEC6008&GJB150.2A-2009.


2. Device features :

2.1. The intelligent control software "temperature and humidity energy-saving control system" with the company's own intellectual property rights is adopted, combined with the patented hardware of utility model "an energy-saving refrigeration system of high and low temperature alternating damp heat test chamber";Compared with the traditional control mode in the same industry, the energy consumption of the whole machine in normal operation saves 40% of electric energy。


2.2. More than 2400 hours of single fault free continuous operation; The operating life of the whole machine is more than 100000 hours, the safety performance has passed the EU CE safety inspection certification。
