The DFHT-RRO dynamic gas dispenser is mainly suitable for preparing standard gases in ppm with nitrogen as the equilibrium gas. Gas detection equipment manufacturers, measurement, environmental protection, petrochemical, universities, medicine and health, laboratories, coal mines and other departments verify gas analyzers and alarms to prepare low-concentration standard gases.

1. Automatic gas distribution according to the set value, gas distribution scheme can be preset, which is convenient for daily repetitive gas distribution work;
2. LCD large screen display, full Chinese menu, touch operation;
3. All standard gases are converted into gases of the required concentration, saving costs;
4. The air treated by the air generator can be used as zero gas, and the ratio is proportioned with the standard gas;
5. High gas distribution accuracy, stable air flow, flow control of the prepared standard gas, that is, the standard gas prepared according to the set flow rate output.
6. The instrument can be distributed with four channels of flow control and more than four channels of flow control, and the flexible operation mode of the gas can be selected.
