Super User MicroTrak 101 Gas Mass Meters & Controllers 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 Industries: General Research / Analytical / Life Sciences & Health / Biopharmaceutical / Life Science / Medical Devices Benefits #twoj_fragment1-1 Applications #twoj_fragment1-2 Specifications #twoj_fragment1-3 Downloads #twoj_fragment1-4 Benefits of Sierra's MicroTrak™ Ideal for OEM, industry and research Full-scale flow ranges under 4sccm (smlm) Proprietary valve orifice design for smooth control at ultra-low flows User-friendly pilot module display interface is front-mounted, hand-held or remote mounted Field adjustment with multifunction pilot module display interface.
