Introducing the new Rapidox 1100
Cambridge Sensotec’s flagship Rapidox 1100Z oxygen gas analyser is being relaunched in November 2018 with a new look, new features and fully upgraded software. First developed nearly ten years ago, the Rapidox 1100 oxygen gas analyser continues to be the company’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 to 100% gas, within inert atmospheres or gases containing VOC’s (volatile organic compounds), 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 updated Rapidox 1100Z has a new 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 1100Z zirconia models now include an updated, superior zirconia planar sensor, providing faster and more accurate trace oxygen measurements. The internal pressure sensor compensates for small changes in gas pressure to ensure that the readings remain stable. A bespoke powerful long-life pump draws in a gas sample at a flow rate set by the user.
With the use of an Ethernet adaptor, the new Rapidox 1100Z 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.
Variations of the standard Rapidox 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 1100Z oxygen gas analyser can also be used to control an external Proportional Flow Control (PFC) valve or a more basic Remote Solenoid Output (RSO). This is particularly useful within inert gas blanketing applications in ovens and furnaces, where the analyser can regulate the level of gas based on the measurement of oxygen via the PFC or RSO control function.
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 1–100% 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.
Cambridge Sensotec has been manufacturing the Rapidox range of gas analysers for over 18 years. The company initially specialised in zirconia oxygen (O2) analysis, before expanding into electrochemical, IR and TCD multigas analysis. The company also developed specialist SF6 analysers for high voltage gear applications to suit customer and industry requirements, and in 2014, the acquisition of Dynascan provided the ability to deliver innovative leak detection systems within the food and pharmaceutical industries. The company now has a global network of fully trained support partners and distributors.
