Middle East MR-DF3 Portable High-Precision Dynamic Gas Distribution Meter Manufacturer, Brand

MR-DF3 portable high-precision dynamic gas distribution meter is easy to carry and can be used for emergency gas distribution work. It can work continuously for more than 20 hours after power failure.

Equipment to realize dynamic gas distribution. The gas distribution part uses imported high-precision mass flow controllers to control the flow rates of multiple gas outputs in different proportions, thereby dynamically realizing the configuration of various gas concentrations. This instrument can be used to test a variety of technical indicators such as linearity, accuracy, and repeatability of gas analyzers. It is an indispensable test tool for calibration, maintenance, and repair of gas analysis instruments as well as a dilution device for fixed concentration gases.

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