Professional manufacturer temperature humidity environmental chamber with multi layers Professional manufacturer temperature humidity environmental chamber with multi layers is simulation under the condition of product in humid climate environment combination(high and low temperature operation storage, temperature cycle, high temperature and high humidity, low temperature and humidity and condensation test, etc.), check whether the adaptability and characteristics of the product itself. Does need to be met the requirements of international standard (IEC, JIS, GB, MIL...).International quantum measurement procedures in order to achieve consistency (including test steps, conditions, methods) to avoid different cognitive,  and narrowing the scope of measurement uncertainty. Kunshan Bositong Instrument Equipment Co., LTD is a professional manufacturer of these kinds of test instruments and offering technical service.
