Rapidox 2100 Oxygen Analyser by Cambridge Sensotec

The Rapidox 2100 is a high-performance oxygen (O2) analyser fitted with a rugged long-life zirconia sensor on a remote cable, together with a type K thermocouple sensor; allowing direct in-process measurement of oxygen and temperature in the sample gas. The sensors provide fast and accurate analysis over the low ppm oxygen range in harsh environments up to 650°C.

Zirconia oxygen sensors are particularly suitable for monitoring inert atmospheres in aggressive industrial applications within manufacturing processes; this includes high-temperature locations and vacuum atmospheres.

In rare instances where zirconia sensors are unsuitable, an electrochemical sensor will be used instead. Electrochemical oxygen sensors are ideal for monitoring high oxygen applications, or where VOC’s, flammable gases, CO, H2 or He are present in the gas sample. Users have a choice between a sensor for low ppm measurements of 1ppm to 1%, or for high percent measurements in the 0-100% oxygen range.

Depending on the specification of the analyser, the sensor is normally housed in a remote metal manifold that allows gas to flow through and over the sensor surface, or provide a vacuum-tight coupling to the sample point in a vacuum application. The exact design of the manifold housing depends on the application and can be situated up to 25 meters from the analyser using optional sensor extension cables. As well as a type K thermocouple sensor which is fitted as standard, a range of optional auxiliary pressure, vacuum and dewpoint sensors are available allowing multiple measurements in one instrument.

The configuration of the analyser allows for the instrument to be panel mounted or supplied within a wall-mountable, IP65 weatherproof housing. The oxygen sensor can then be positioned remotely, up to 25 metres away in either a separate cabinet or as a standalone sensor. A printer can be attached to the instrument using the serial port for permanent record keeping of results. 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.
