The new Rapidox ZR3 is the next generation of process gas analyser. This unit is capable of measuring 3 different streams of gas sequentially using just one analyser. Perfect for applications that require oxygen analysis in inert gases and CO2, the Rapidox ZR3 can measure O2 from 1ppm to 100%. Such applications include nitrogen generator purity checks, nitrogen blanketing in mass flow soldering and semiconductor related diffusion drying furnaces.

The Rapidox ZR3 can be controlled using the bespoke software supplied with the analyser, allowing the user to set sampling times for each channel, program high and low gas alarms and ‘name’ channels for easy recognition. If the unit is required for a standalone application all sequences can be programmed via integrated user friendly control panel with intuitive menu system.

With extremely low maintenance costs and a very robust zirconia sensor the ZR3 gives the user high reliability and pinpoint accuracy over the full O2 range. The unit is also available in a panel mount configuration.
