| Rapidox 3100 Unit: The Rapidox 3100 is an attractive metal instrument with plastic membrane front panel. The unit weighs approximay 7kg and is fitted with adjustable rubber feet. The unit is mains powered （110/240V 50/60Hz） and is supplied with mains cable. Case dimensions W=350mm; D=263mm; H=150mm. Response, Accuracy and Precision: Sensor response time is typically 5 seconds for a 90% response involving a step change in composition. A change between 21% and * can be recorded in less than 4 seconds depending on sampling flow-rates. High accuracy is maintained between calibration points. Accuracy is ± 1% of the actual measured oxygen content with a precision of ± 0.5%. Outside calibration range accuracy is typically ± 2.5%. An on-board pressure sensor makes corrections for fluctuations in gas pressure resulting in enhanced stability Display: The display on the front of the instrument is a large back-lit LCD with 2 X 16 characters 9mm high. The display can be read quite easily from a distance of several meters. Display update rate is user-programmable. Displays four significant figures of oxygen （O2）. The display notation （percent, ppm, exponential or 'automatic'） is user selectable. Values of oxygen below 10e-1ppm are always displayed using exponential notation. Working range is 10e-20ppm （=10e-24%） to *. Temperature display: type 'K' thermocouple 0 to 999 degrees Celsius. Sensor Head: The sensor is located inside the analyser and gas is drawn over the sensor head using a top-of-the-range Medo linear-motor-driven free piston vacuum pump manufactured by Nitto; a world leader in pump technology. The pumps are exceptionally quiet （40 dB/m or less）. The gas is sampled using flexible tubing that connects to the front panel via push fit pneumatic couplings. The flow rate is controlled using a flow gauge / needle valve on the front panel and is adjustable from 0 to 4 litres per minute. Sensor life expectancy is in excess of 35,000 hours. Calibration: Simple and fully flexible calibration procedure requires two calibration gases （ambient air is normally used as calibration gas no. 1）. Gas compositions are user-selectable and programmed into the Rapidox via the keypad on the front panel. Factory pre-sets can be reloaded to allow the unit to be 'rescued' from a failed calibration. Rapidox is calibrated using the keypad on the front panel. Display changes into calibrate mode to inform user of progress. Operating temperature: Gas temperature entering the analyser must not exceed 125oC. The tubing inside the analyser is PTFE which is rated to 250oC. The Rapidox unit normal operating temperature is 5-35oC. Outputs: RS232 outputs on demand values for oxygen （ppm）, temperature （Celsius）, time （hh:mm:ss） and date （dd:mm:yy in the UK, mm:dd:yy in the USA） once per second. Outputs can be data-logged using the software provided. Standard analogue outputs are 0-5V and 4-20mA and alarm （high and low condition） circuits. These outputs are fully user-programmable via the keypad on the front panel. | Oxygen gas analyserCB8Rapidox 3100 |
