Model 822 & 824 Analog Mass Flow Meter

Description

The Top-Trak® Mass flow meter directly measures the mass flow rate of gases in flow ranges from 0-10 sccm up to 0-50 slpm. The Model 822 & 824 are for measurement of air and ALL inert gases & mixtures.  Both models serve a wide range of inert gas flow applications including process control, flow research, OEMs, gas panels, and cell culture maintenance

In addition, both models offer standard 0-5 VDC or 4-20mA output signals. The Model 822 is equipped with a large tiltable LCD readout available in your choice of engineering units.  The LCD readout can be mounted on the instrument or on a remote panel. The Model 824 is a compact OEM configuration that comes without the LCD readout. Sierra’s Platinum Sensor Technology to eliminate zero-drift and create excellent long-term reliability is utilized in the design of both Models.
