Gas Mass Flow Meter & Controller | Ultra Low

Ultra Low-Flow Meter, High Performance Digital Gas Mass Flow Meters & Controllers

The MicroTrak™ 101 from Sierra Instruments measures and controls micro mass flows of gas (previously thought to be too low for a reliable reading).

Sierra specifically designed the MicroTrak™ for flow ranges under 4 sccm (smlm) with a minimum controllable mass flow rate of 0.08 sccm (smlm). The Model 101 is a specialised and highly engineered instrument for those who need accurate and reliable micro mass flow control of clean gases including corrosives and toxics.

MicroTrak™ is based on Sierra’s award-winning family of digital instruments. As a result, ease of operation, field configuration, multi-gas capability and application flexibility are standard features.

MicroTrak's NIST traceable accuracy is backed by Ssierra's 10-point, primary standard calibration over the entire flow range. The low pressure flow meter has a strong and flexible control valve with accessible PID valve tuning to assure best speed and reliability. Custom valve orifice sizing yields full-range stability.

Featuring:

Measure and control flow rates down to 0.1 sccm (smlm)
Increase efficiency with true, digital high-performance
Navigate easily with large multifunction display interface
Save time by making adjustments in the field
Configure up to 10 gasses with one instrument
