The aerospace engineering clean room is a workshop for the production of rockets, satellites, aircraft, engines and other aerospace products used in aerospace and aviation. The production of these precision instruments has high requirements for the quality of the air environment in the clean room. In addition to the strict requirements for particulates in the air, there are also strict requirements for temperature and humidity, vibration, noise, etc., and the air suspended particles count concentration monitoring, one-way flow section wind speed detection, non-one-way flow air outlet air volume detection, air supply pipe air volume detection, differential pressure detection, temperature detection, relative humidity detection, air flow direction detection, self-cleaning time detection, electrostatic detection, noise detection, illuminance detection, high-efficiency filter in-situ scanning leak detection, micro-vibration detection must be tested in order to produce qualified products.
