Gas Mixing/ Dilution/ Calibrator Systems
PTC works with Environics to supply a complete range of computerized gas flow instrumentation such as gas mixing, dilution and calibration systems.

Environics’ gas mixing technology is based on very precise control of thermal mass flow controllers. Normally, thermal mass flow controllers offer an accuracy of +/- 1% of full-scale flow. However, when combined with Environics computerization and calibration, this accuracy specification is improved to +/- 1% of setpoint. Their calibrators and dilution systems exceed the accuracy required by the US EPA for Ambient Calibrators (ref: Method 205, 40CFR51, 40CFR60, 40CFR75).
