Michell Instruments PCR portable calibration rig for gas analysers

The Michell Instruments PCR portable calibration rig is a mobile gas blender using premium mass flow controllers housed in a tough transport case that can be used for gas analyser calibration with a large variety of applications and analysers. It can mix two or three gases from air, oxygen, nitrogen, carbon dioxide, methane and hydrogen, and is easily controllable so that the perfect blend can be achieved for the application.

Provided the user has the appropriate gas cylinders available, it is possible to ‘factory’ calibrate an analyser such as the company’s XTP601. For example, an analyser range of 0-10% O2 in N2 could be calibrated with synthetic air and N2.

A field calibration of an analyser can be carried out in under one hour including set-up time.  For a complete factory calibration, with multiple calibration points (to change the range/background/both), four hours would be all that is required. These timescales represent a minimal downtime compared to the alternative of sending the instrument away for calibration.

Although the unit is designed for field calibrations, it can also be used in a laboratory to mimic changing process gases for research work.
