Industrial Gas Mixer IGM

The IGM industrial gas mixer developed by Gometrics allows gas handling operations to be carried out. Thanks to its versatile software and touch screen, the IGM allows the instrument technician to optimally generate the desired gas mixture required for his process. Typical applications include calibration of gas detectors, linearity analysis in analysers, packaging for food preservation, surface treatment and biochemical reactors.

Robustness, accuracy, ease of use and safety have been prioritised in its design. Optionally, it can be supplied with an EN17025 accredited certificate for gas flow.
