Multi-component gas-liquid hybrid dynamic distribution system XDB-D02

First, dynamic gas distribution system introduction:

XDB-D02 can be used to test a variety of technical indicators such as linearity, accuracy and repeatability of gas analyzers. It is an important test tool for the verification, maintenance and repair of gas analysis instruments and the generation device of fixed concentration gas. Using high precision injection pump and constant temperature heating device, combined with high precision mass flow controller to vaporize and dilute the liquid to achieve the function of liquid distribution. The XDB-D02 is a combination of liquid gasification, dynamic gas distribution and mixed gas and liquid distribution equipment.

Second, the application field of dynamic valve system:

The dynamic gas distribution system is suitable for metrology institutes, verification institutions, laboratories, scientific research and development, detector manufacturers and so on.

Three, the main characteristics of dynamic gas distribution system:

1, support gas, liquid simultaneous gas distribution and mixed gas distribution;

2, flow control adopts closed-loop fuzzy control technology, fast response speed, accurate flow control;

3, zero gas pressure and cylinder gas pressure can be monitored in real time to ensure that the gas supply pressure meets the requirements of the instrument;

4, large LCD screen, Chinese display, easy to operate;

5, multi-signpost gas input interface, avoid the tedious work of replacing a variety of cylinder gas.
