The Rapidox 1100 oxygen gas analyser

First developed nearly ten years ago, the Rapidox 1100 oxygen gas analyser continues to be the Cambridge Sensotec's best-selling and most versatile oxygen instrument, due to its speed and accuracy of measurement, ease of use, calibration and ultra-long life sample pump.

The Rapidox 1100 gas analyser range includes a choice of oxygen sensors designed for measuring ppm levels, suiting a wide range of applications. For example; gloveboxes, welding, monitoring inert atmospheres within solder reflow ovens, additive manufacturing, medical and food packaging testing applications and metal heat treatment amongst others.

The Rapidox 1100 has an OLED screen which now delivers improved visibility from every angle, with four lines of information displayed. The Rapidox 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 1100 zirconia models now include an updated, superior zirconia planar sensor, providing faster and more accurate trace oxygen measurements.

With the use of an Ethernet adaptor, the Rapidox can be connected directly to a network and accessed remotely via a PC in the same network or over the internet. The updated Rapidox software allows the user to turn their PC into a giant remote Rapidox display emulator. This is particularly useful for applications where the analyser is based in a remote laboratory and needs to be monitored from another part of the building or anywhere with an internet connection.

Modbus RTU is now installed as a standard communications protocol; ideal for when used in conjunction with a PLC or other external control systems. Other new features include an enhanced calibration allowing up to five separate test gases to be used instead of the standard three. The calibration quality can also be gauged by the incorporation of a live R-squared function. Individual calibration data, together with other critical parameters such as ambient conditions, historical alarm events, machine run time are now stored and displayed in a new system info menu. The alarm relays now have a latching option to fall in line with standard equipment features. The password system has been updated and the screen display can now be configured to include balance gas values as well as the standard oxygen and pressure readings.

The Rapidox 1100 range is available with many sensor variations including a choice of two electrochemical oxygen sensors, one for low ppm measurements of 1ppm to 1% and another for high percent measurements in the 1ppm to 30% oxygen range. Electrochemical sensors are ideal for applications where VOC’s or flammable gases are present in the gas sample. Other special variations for measuring CO₂, CO, H₂, He and Ne and Xe using Infra-Red (IR) and thermal conductivity (TCD) technology are available.
