Precision Flow Lab, LLC is a newly established mass flow controller service center in Tempe, Arizona. Our service responsibilities are to provide routine maintenance, troubleshooting, and performing in-situ testing on a wide variety of MFC’s and Baratrons. Our superior technical infrastructure is coupled with 30+ years of experience repairing, servicing, and selling refurbished mass flow controllers.

Precision Flow Lab uses DH Instruments/Fluke state of the art primary molbox calibration stations, allowing for calibration to less than +/- 1% of full-scale accuracy, which exceeds most OEM’s specifications. We calibrate and repair most mass flow controllers from legacy analog devices to the latest digital RS-485 types, including some Devicenet models using OEM software. We are highly trained professionals capable of supporting most major OEM brands.

We use a MKS PVS-6 state of the art vacuum system to perform Baratron servicings.
