Rapidox 7100 Multigas Analyser

Product Information

The Rapidox 7100 Multigas Analyser is a high specification instrument designed for the analysis, control and monitoring of process gas in a wide range of industries. It allows the option of selecting multiple gas sensing configurations to suit the particular application. The analyser is housed within a 19″ (482mm) enclosure for convenient mounting into an industry-standard test equipment rack.

Up to seven gases are simultaneously measured using a range of high precision gas sensors; each sensor is specially designed and calibrated to avoid any cross-interference effects with the background process gas. Safety is ensured by the inclusion of flashback arrestors in the gas measuring circuit where required. Measurable gases include amongst others: CO2, CO, H2O, O2, C2H4, SO2, CH4, H2 and H2S.

When configured for applications where the gases are energy-containing (e.g. Biogas, Syngas) the calorific value of the gas sample is determined using thermodynamic calculations and simultaneously logged and displayed on-screen.

Product Information

An optional pump enables two modes of operations. For samples that are taken from a gas source at atmospheric pressure or below, the pump is activated to draw a sample through the analyser. Alternatively, the pump can be deactivated when sampling from a source at greater than atmospheric, allowing the gas to flow through the analyser. Gas flow is regulated manually via a rotary knob on the fascia and displayed electronically on the screen.

Standard features 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.

A 7″ (180mm) full-colour touch screen interface with soft menu keys allows for easy operation in either permanent monitoring or sampling modes. All data is continuously logged for review and inspection and Excel compatible data can be downloaded via a USB memory stick.

Cambridge Sensotec offers a range of Rapidox servicing options. Regular gas analyser calibration significantly increases the measurement, reliability and repeatability of equipment. A full service is available via state-of-the-art automated stations, designed to calibrate Rapidox gas analysers accurately and efficiently.
