Is your oxygen analysis accurate?

DSC5830With the Rapidox 2100 zirconia oxygen analyser, sub-ppm measurements to 30% of oxygen gas can be analysed rapidly and accurately. The robust remote sensor, connected via a 2-metre cable*, can be placed within the heart of the application, providing 24/7 of reliable gas analysis. Gas temperatures of up to 600°C can be analysed by the sensor, with an additional Type K thermocouple providing independent temperature measurements. Auxiliary sensors can be added to suit the application for pressure or dew point.

An alternative to the zirconia sensor is an optional remote electrochemical oxygen sensor available for measuring 0 – 100% oxygen. Electrochemical sensors are ideal for applications where VOC’s or flammable gases are present in the gas sample. The electrochemical oxygen sensor is housed within a stainless-steel bulkhead, together with an integrated pressure sensor which compensates for small changes in gas pressure to ensure that the readings remain stable.

The Rapidox 2100 is available in a bench mounted configuration, or with a bezel front panel to incorporate the instrument within a rack.  Additionally, the Rapidox 2100 can be supplied within a wall mountable, IP65 weatherproof housing. The zirconia sensor can then be positioned remotely up to 26 metres away either in a separate cabinet or as a standalone sensor. For customers requiring seamless integration into their product or process, the Rapidox can also be supplied as an OEM solution.

Standard features on all models include two fully programmable alarm circuits (volt free contacts), programmable analogue outputs (0-10V and 4-20mA), easy calibration (user selectable gases), RS232 / RS485 communications and complete data-logging software.

Ideal applications can include: Additive manufacturing, combustion, glove boxes, inert gas blanketing, manufacturing processes and metal heat treatment facilities.

Latest update: The Rapidox 2100 oxygen gas analyser is undergoing an upgrade and redesign in line with the new Rapidox 1100 model launched last year. Equipped with updated features, such as a new OLED (organic light-emitting diode) screen and updated superior zirconia planar sensor providing faster and more accurate trace oxygen measurements, the Rapidox 2100 also includes new blue fascia making it easier to identify from other equipment in your workplace. The new Rapidox 2100 oxygen gas analyser will be announced later in 2017.

*Other lengths of cable are available on request.
