main feature
- Complies with the relevant standards involving gas distribution instruments in HJ57-2017, HJ76-2017, HJ604-2017, HJ38-2017, supports gas mixing and distribution of multiple components, and can distribute ppb level, ppm level, percentage level, etc. concentration standard gas;
- It can be customized according to customer needs for dual-channel, three-channel, multi-channel and other composite gas distribution;
- It adopts high-quality components such as high-precision stainless steel mass flow controller, stainless steel quick-plug OD6/4mm gas interface, and high-precision rotor flowmeter to ensure high system gas distribution accuracy and reliable quality;
- Large-size LCD screen, the system runs more stably and the operation is easier;
- Adopts 19-inch 4U chassis, which is easy to integrate into the cabinet;
- Flow control adopts closed-loop fuzzy control technology, with fast response and accurate flow control;
- Zero air pressure and cylinder air pressure can be monitored in real time to ensure that the air supply pressure meets the instrument requirements;
- The gas path cleaning function in the system can ensure the accuracy of each gas distribution and the long life of the equipment;
- Dual output, automatically balances the inlet pressure of the detection equipment;
- The gas distribution instrument is equipped with temperature compensation, so customers do not need to consider the influence of temperature on equipment operating data at different temperatures;
- No preheating time is required, gas distribution can be started immediately after turning on the machine;
- Independent intellectual property rights, including invention patents and software copyrights.
