Cambridge Sensotec specialises in the design and manufacture of gas analysis equipment under the Rapidox brand name.

The Rapidox range includes high precision, scientific gas analysis equipment designed for use in industrial processes, quality control applications, environmental monitoring and research and development experiments.

Cambridge Sensotec has now launched the Rapidox 1100 Oxygen Gas Analyser. Benefitting from over 15 years of reliable and accurate service, the company’s instrument has undergone a redesign including features such as:

  • An updated superior zirconia planar sensor providing faster and more accurate trace oxygen measurements, maintaining the desired levels oxygen in your process. The 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.
  • A four-line OLED (Organic Light-Emitting Diode) display that delivers improved visibility from every angle with four lines of information displayed, making the Rapidox 1100 easy to identify in laboratories, manufacturing plants or test facilities due to its new dynamic blue fascia design.
  • Now incorporating the Modbus RTU (Remote Terminal Unit) data communications, ideal for when used in conjunction with a PLC (Process Logic Controller) or other external control systems.
  • With the use of an Ethernet to serial adaptor, the Rapidox can now be connected directly to a network and accessed remotely via a PC in the same network or over the internet. The Rapidox software operates the Rapidox as if it were connected directly to the PC. 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.

The Rapidox 1100 gas analyser is available with 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, solder reflow ovens, additive manufacturing and metal heat treatment amongst others.

Standard features on all models include two fully programmable alarm circuits (volt free contacts), programmable analogue outputs (0-10V and 4-20mA), easy calibration, RS232/RS485/Modbus communications and comprehensive instrument control/data-logging software.
