The unit is a preparation device for standard gas and mixed gas, which was developed in accordance with GB/T 14070 Gas analysis--Preparation of calibration gas mixtures--Manometric method. It is used to prepare standard gases of micro-components under a precision standard balance. It can be used to produce a small batch of constant-quantity mixed gas.
Compared with conventional gas proportioning devices, MGM-2000 gas proportioning unit has the following advantages:
1. The unit adopts a high-precision low-drift pressure sensor to display pressure in each section. It eliminates multiple pressure gauges used in conventional gas proportioning devices, making the pressure display more intuitive and simpler.
2. The unit adopts a zero-dead volume gas circuit design.
3. It adopts a micro-adjusting valve that accurately adds target components.
