Valve apparatus

High precision dynamic valve valve XDB-HD3

1. Application fields of gas distribution instrument:

It is suitable for calibration of gas analyzers and preparation of standard gas samples for testing in factories, scientific research and laboratories.

Two, the main characteristics of the valve instrument:

1, support a variety of components of gas pairwise mixed gas distribution, can be allocated ppb level, ppm level, percentage level and other concentrations of standard gas.

2, the use of high-precision stainless steel mass flow controller, high-precision rotameter and other high-quality components to ensure that the system has high precision and reliable quality.

3, large screen LCD screen, Chinese display, the system is more stable, easier to operate.

4, flow control adopts closed-loop fuzzy control technology, fast response speed, accurate flow control.

5, 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.

6, the gas path cleaning function in the system can ensure the accuracy of each gas distribution and the long life of the equipment.

7, no preheating time, boot can be distributed.
