ZZC
The DFHT-RRO dynamic gas dispenser is mainly suitable for preparing a standard ppm grade gas with nitrogen as the equilibrium gas.Gas detection equipment manufacturers, measurement, environmental protection, petrochemical industry, universities, medicine and health, laboratory, coal mine and other departments to verify the gas analyzer and alarm and prepare low concentration standard gas.
main features
1. Automatic air distribution according to the set value, and the gas distribution scheme can be preset to facilitate the daily repetitive gas distribution work;
2. LCD large screen display, full Chinese menu, touch operation;
3. All the standard gas is converted into the required concentration of gas to save the cost;
4. The air treated by the air generator as zero gas is matched with the standard gas;
5. High gas distribution accuracy and stable air flow. The formulated standard gas can be controlled for the formulated standard gas, and the formulated standard gas can be output according to the set flow rate.
6. The instrument can be four flow control and flow control above four gas distribution, and the gas can be optional flexible operation
