Oxygen Analyser

Product Description

Oxygen Analyser The Oxygen Analyser measures oxygen concentrations from percentage levels to a fraction of parts per million (ppm) in clean gases. Packaged on a 19 rack mounting enclosure, it uses a oxygen sensor to provide accurate measurement with minimal interference from other gases. The unique cell and heater design gives very fast warm-up times, rapid response, and long sensor life. Specification of Oxygen Analyser 1. Display Multi-digit LCD, character height 12.7mm 2. Range 0.1ppm to 100% oxygen, autoranging 3. Display resolution From 10% to 100%: 0.1%From 0.5% to 9.99%: 0.01%From 500ppm to 4999ppm: 10ppmFrom 50ppm to 499ppm: 1ppmFrom 5ppm to 49.9ppm: 0.1ppmFrom 0ppm to 4.99ppm: 0.01ppm 4. Accuracy 100% to 100ppm: 2% of reading or better99ppm to 10ppm: 1ppm0.1ppm to 9/9ppm: 0.2ppm 5. Stability Better than 2% of reading or 0.5ppm/month, whichever is greater 6. Sample flow Between 100 and 300ml/min for optimum operationSpeed of response in clean inert atmospheres% levels: less than 0.5s for 90% changeLevels from 100 to 10ppm: less than 5s for 90% changeLevels less than 100ppm: less than 30s for 90% changeWhen the cell is stabilised/conditioned at low levels, response to changes at that level is of the order of 3 to 4sSample inlet pressure (no pump fitted)10mbar minimum8bar maximumSample temperature (at analyser)100C maximumSampling system materialsMaterials include: nickel, brass, aluminium, stainless steel, platinum, zirconia, alumina, PTFE and nitrile-rubberSample connection (located on back panel of unit)Captive seal compression fitting suitable for 0.25inch (6mm) outside diameter tube 7.
