Mass Flow Controllers and Liquid Flow Meters


Baratron  Capacitance Manometers & Valves

  • All pressure devices are calibrated on automated MKS Vacuum Diagnostic Systems.

  • These systems allow our technicians to test from 10 Mtorr to 5000 Torr with +/- .08% of reading accuracy.

  • Provide a complete service, including sensor and PCB replacement if needed.

  • Re-ranging service for all manometers as well as calibration of pressure controllers and pressure devices is available.

  • Our exacting rebuild process stars with dismantling of each valve, which is subsequently cleaned and inspected.

  • Using a proprietary system purpose built for testing valve functions, Semigroup analyzes motor function.

  • Checks valve positioning, validates leak integrity and tests flapper assembly functions on every valve.

  • Based upon test results each valve is rebuild as needed to conform to manufacture's specifications.

  • New seal and bearing kit is installed in every valve.

  • Teflon recoating is applied as needed.

  • Prior to packaging, a three phase quality assurance test represents the final phase of our rebuilding process.
