More Information
Sierra Instruments 840L-2-0V1-SK1-D-V1-S1 Low Flow Gas Mass Flow Controller Overview
Features:
- Accurate and Reliable
- Stainless Steel Construction
- Flow Ranges from 0-10 SCCM to 0-5600 SLPM
Proven by over 25 years of field installations, the Side-Trak product line is distinguished by its patented, cleanable, large-diameter sensor tube and the reliability and serviceability that this feature provides. Because a microscopic layer of contamination has a major effect on small diameter sensor tubes, many mass flow meters and controllers suffer, over time, from degradation of accuracy or repeatability.
The Side-Trak sensor is not only larger in diameter than most other MFMs and MFCs, but it is mounted along the side of the flow body to provide access ports at either end. In the event of clogging or contamination, it can be cleaned with the 0.03-inch diameter cleaning rod available from Sierra.
The Sierra Instruments 840L-2-0V1-SK1-D-V1-S1 Low Flow Gas Mass Flow Controller may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).

We found Artisan when our PXI Chassis broke, which shut down our production line. We were up and running in less than a day because they shipped overnight and talked our tech guys through the installation over the phone. ATG saved the day big time!
