The Rapidox 1100 oxygen gas analyser is the company’s most cost-effective and versatile range of gas analysers fitted with either zirconia or electrochemical type gas sensor. The zirconia oxygen sensor is the most common solution providing fast and accurate gas analysis over the range 1ppm to 30% O2 and is particularly suitable for aggressive industrial applications.

Users have a choice of two electrochemical oxygen sensors: one for low ppm measurements of 1ppm up to 1% and another for high percent measurements in the 1ppm to 30% oxygen range. Electrochemical sensors are ideal for high oxygen applications or ppm applications where VOC’s, flammable gases, CO, H2 or He is present in the gas sample.  A special “oxygen clean” version of the high range analyser is also available.

Together the three sensor types offer an oxygen measuring solution for almost any application possible.

Other variations of the model include a three-channel multiplex version, which allows for three gas streams to be sampled from separate points. Gases can be analysed in sequence or at intervals set from the controls (front keypad or software).

The Rapidox 1100 can also be used to control an external proportional flow control valve (PFC) or a single solenoid relay using a remote signal output (RSO). These are particularly useful within inert gas blanketing applications, where the analyser can regulate the level of gas based on the measurement of oxygen via the PFC or RSO control function.
