Rapidox 3100: Introduction

The Rapidox 3100 oxygen analyser allows fast and accurate oxygen analysis over the full oxygen range (10e^-20ppm to 100% O₂). The Rapidox 3100 analyser provides continuous on-line oxygen analysis, with a typical response time less than 5 seconds for a 90% response to a step change in gas compositions.

At the heart of the Rapidox 3100 is a top-of-the-range Medo linear-motor-driven free piston vacuum pump manufactured by Nitto; a world leader in pump technology.  The pumps are exceptionally quiet (40 dB/m or less).  The flow of gas can be adjusted using the flow gauge / needle valve on the front panel of the analyser.  Typical flow rate is 1 litre per minute

The sensor head is located inside the analyser and comprises a zirconia ceramic tube that needs to be heated to 650°C before it will conduct oxygen ions. The analyser supplies heat to the sensor, which is controlled very accurately by a regulated power supply incorporated in the instrument.  An internal pressure sensor compensates for small changes in gas pressure to keep the readings stable.

The analyser is packed with features including fully programmable alarm circuits, programmable analogue outputs, easy calibration (user selectable gases), RS232 communications, independent type K thermocouple and a full set of communications / data-logging software.

The Rapidox 3100 incorporates our highly successful sensor 'clean' mode which is accessed via a push button on the rear of the instrument. This removes deposits on the sensor surface that cause drift if allowed to accumulate.
