Redesigned Oxygen Gas Analyser provides Accuracy and Versatility

The Rapidox 1100 oxygen gas analyser continues to be the company’s best-selling and versatile instrument due to its accurate and reliable service for over 15 years. Cambridge Sensotec is proud to announce a new design for the gas analyser with exciting enhancements.

A new OLED (organic light-emitting diode) screen now delivers improved visibility from every angle with four lines of information displayed. The Rapidox 1100 is easy to identify in laboratories, manufacturing plants or test facilities due to its new dynamic blue fascia design.

Additionally, for low ppm oxygen gas measurements, the Rapidox 1100Z models now include an updated zirconia planar sensor; providing a more effective sensor heater design, faster response time and superior service life.

An internal pressure sensor compensates for small changes in gas pressure to ensure that the readings remain stable. A powerful long-life pump draws in a gas sample at a flow rate set by the user between 0-1 litres per minute.

The Rapidox 1100 range are available in many variations including a choice of two electrochemical oxygen sensors, one for low ppm measurements of 1ppm to 1% and another for 1–100% oxygen range. Electrochemical sensors are ideal for applications where VOC’s or flammable gases are present in the gas sample.

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 oxygen gas analyser can also be used to control an external proportional flow control valve (PFC). This is 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 control function.

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.

The Rapidox 1100 oxygen gas analyser range is well suited to a wide range of applications within research and development, laboratories, medical and food packaging testing.
