Temperature and humidity chamber as temperature, humidity and chief test equipment, electrical and electronic products, as well as the original device, other material stored in temperature and humidity of the environment, transport, use of adaptive testing performance, the use of the market prospects very large. Maximize product efficiency, improve product life, maintenance measures on the temperature and humidity chamber need all broken up, more professional to use the equipment, as I used to. 1, the installation location required temperature and humidity chamber floor flat, well-ventilated, free of flammable and explosive corrosive gases and dust. Leave appropriate space for maintenance equipment around, not near strong electromagnetic fields, radiation sources in order to avoid measures interference. The test chamber with humidity control, the internal settings of the water tank, is conducive to the maintenance of equipment, the test chamber should be available next drainage floor drain. 2, the device does not work time, when lower winter temperatures damage the pipeline in order to prevent the equipment inside I Water Street East, should maintain the storage environment of the test chamber> 0 ° C. 3, on the water in time, propose to use pure water, distilled water, deionized water, resistivity ≥ 500.m, more conducive to test precision and maintenance of the equipment. 4, regularly clean the surface of the test chamber to keep the equipment clean, prevent hydrocephalus and impurities pollution box. 5, the periodic cleaning refrigeration system, especially brass and bottle body. Regular view Freon margin.
