Rapidox 3100D Dual Gas
Rapidox Dual-Gas Analyser for O2 & H2O
Bench-mounted dual gas analysers for O2 and a choice from CO2 CO H2O and N2O. Fitted with a high performance zirconia oxygen sensor and a latest generation infra-red sensor for high speed and accurate dual gas analysis. Customer specified range of gases for maximum accuracy. Fitted with a powerful internal sample pump for on-line continuous measurements in inert gases with full data-logging and calibration facilities. Type K thermocouple input included as standard.
The Rapidox 3100D Dual Gas O2 / H2O Analyser
The Rapidox 3100D dual gas O2 / H2O (moisture) analyser allows fast and accurate oxygen analysis over the full oxygen range (10-20ppm to 100% O2) and a range of H2O concentrations (measured in terms of dew-point) from -100°C to +20°C dp. The analyser provides continuous on-line analysis, with a typical response time less than 5 seconds for a 90% response to a step change oxygen gas compositions and 180 seconds for dew-point. The dew-point sensors are OEM modules provided by Michell Instruments. The display can be configured to read in terms of dewpoint (°Cdp or °Fdp) or ppm(v) by the user.
At the heart of the Rapidox 3100D is a top-of-the-range linear-piston vacuum pump manufactured by Nitto; a world leader in pump technology. The pumps are exceptionally quiet (40 dB/m or less). The flow of gas can be adjusted using the flow gauge / needle valve on the front panel of the analyser. Typical flow rate is 1 litre per minute The oxygen sensor head is located inside the analyser and comprises a zirconia ceramic tube that needs to be heated up to 650°C before it will conduct oxygen ions. An internal pressure sensor compensates for small changes in gas pressure to keep the readings stable.
The dew-point sensors are high precision transmitters that are fully factory calibrated and is supplied with its own Calibration Certificate, providing direct traceability to both UK (NPL) and US (NIST) Humidity Standards The sensor is certified at thirteen dew-point levels across its operating range against a certified reference hygrometer, using a mass-flow humidity generator system as a source of reference calibration gas.
The analyser is packed with features including fully programmable alarm circuits, programmable analogue outputs, easy calibration (user selectable gases), RS232 / RS485 communications, independent type K thermocouple and a full set of communications / data-logging software. Full data logging of O2 & H2O together with temperature and pressure is possible using the MS-Excel compatible logging software.
