DFHT-PRO dynamic gas distributor/standard gas dilution meter has high gas distribution accuracy and stable air flow, and can control the flow of the prepared standard gas, that is, the standard gas prepared according to the set flow rate output. The equipment automatically distributes gas according to the set value, and the gas distribution scheme can be preset, which is convenient for daily repetitive gas distribution work. DFHT-PRO dynamic gas distribution instrument is used to test gas analyzers and alarms for gas detection equipment manufacturers, measurement, environmental protection, petrochemical, universities, medicine and health, laboratories, coal mines and other departments to prepare low-concentration standard gases.
