Multi-gas analyzer: oxygen (O2), carbon monoxide (CO)
ISO 9001, 0.1ppm - 1% O2, 0-100% CO | Rapidox 3100LB
Cambridge Sensotec
The Rapidox 3100LB dual gas O2 / CO analyser allows accurate oxygen analysis over the range 0.1ppm to 1% O2 using a ppm electrochemical oxygen cell, as well as a range of CO concentrations from 0-3% up to 100%. This low O2 range analyser is designed for applications where a zirconia sensor is not suitable. This includes applications where the measurement gas contains VOCs, solvents, fuels, helium or hydrogen.
The dual gas analyser provides continuous on-line oxygen and carbon monoxide analysis, with typical oxygen analysis response time of less than three minutes from 1% down to 1000ppm. Below 10ppm response times are considerably longer due to the way electrochemical sensors work. The dual gas analyser is fitted with a cell housing which allows the reading to stabilise quickly and is fully temperature and pressure compensated for enhanced accuracy.
At the heart of the Rapidox 3100LB is a Nitto motor-driven diaphragm vacuum pump. The flow of gas can be adjusted using the flow gauge/needle valve on the front of the analyser. Typical flow rate is 1 litre per minute. The O2 cell is sensitive to exposure to high concentrations of oxygen, including air, and to prevent damage the unit is fitted with solenoid valves to keep the cell in the measurement gas at all times. An internal pressure sensor compensates for small changes in gas pressure to keep the readings stable.
The dual gas analyser has features including fully programmable alarm circuits, programmable analogue outputs, easy calibration (user selectable gases), RS232 (optionally RS485) communications and a full set of communications/data-logging software that is MS Excel compatible.
