Rapidox 2100-FGA Forming Gas Analyser
Product Information
The Rapidox 2100-FGA Forming Gas Analyser is a special variant of an existing zirconia oxygen analyser which allows fast and accurate oxygen analysis over the full oxygen range to extremely low levels commonly found in hydrogen forming gas.
The sensor measurement range is extended down to 10E-30ppm O2 to cover the ultra-low oxygen partial pressures in forming gas mixtures. The sensor is designed for high-temperature operation which can be extended up to 1000°C when using one of the available insertion sample tubes.

The Rapidox provides continuous on-line oxygen analysis, with a typical response time of fewer than 4 seconds for a 90% response to a step-change in gas compositions. In addition to this, the analyser performs complex thermodynamic equations to calculate the H2O dewpoint of the forming gas. These calculations have been verified by a resident thermodynamics expert at Cambridge University. The operator simply dials in the hydrogen content of the forming gas and the analyser does the rest. The dewpoint is then displayed simultaneously on-screen in either °Cdp or ppmV.
The temperature is determined either from the sensor head (up to 660°C) or above this, the temperature is recorded using the type K thermocouple which is fitted as standard.
The analyser is packed with features including programmable alarm circuits, programmable analogue outputs, easy calibration (user selectable gases), RS232 & Modbus communications and complete communications / data-logging software. Additional sensors may be attached via the auxiliary socket which will read most standard 4-20mA transmitters. Currently, the Rapidox 2100-FGA can be configured to read pressure or vacuum. A vast array of special fittings, filters and manifolds are available for both oxygen and auxiliary sensors, to make this a completely versatile instrument that can be installed almost anywhere. Depending on the application, the sensors can be located up to 25 meters from the analyser using optional sensor extension cables.
The instrument can be panel mounted (19″) or supplied within a wall-mountable, IP65 weatherproof housing. The oxygen sensor can then be positioned remotely, in either a separate cabinet or as a standalone sensor. A printer option is also available. All Rapidox analysers come with full Windows software that allows for remote configuration and monitoring of readings, as well as a full data-logging package that includes live-time graphing of each sensor channel.
Finally, the Rapdox 2100-FGA complies with EMC Directive 2004 / 108 / EC. UL/ETL Certification Number: UL-61010-1.
