O2 Gas Analyzer Transdox 3100Z O2

The Transdox 3100Z oxygen analyzer allows fast and accurate oxygen analysis over the full oxygen range 10-20ppm to 100% O2 in steps of 0.01%. CO2 concentration, from ppm up to 100% & CO concentration, from 0-3% to 0-100% (range specified by the customer at the time of ordering). H2O concentrations from either -60°C to +20°C or -100°C to +20°C dp (dew-point). Chlorine at a range of 0-60ppm. N2O concentrations 0-1000ppm. The analyzer provides continuous on-line oxygen analysis, with a typical response time less than 5 seconds for a 90% response to a step change in gas compositions, 30 seconds for CO&CO2&H2O&N2O and 60 seconds for Cl2. The dew-point sensors are OEM modules.

The analyzer contains a powerful Nitto motor-driven vacuum pump which draws a gas sample at a rate that can be set by the user using the flow gauge/needle valve on the front panel. Typical flow rate is 1 liter per minute. Alternatively the pump can be independently switched off and operated under flowing gas conditions.

The zirconia sensor head is located inside the analyzer and needs to be heated to 650°C before it will conduct oxygen ions. The analyzer supplies heat to the sensor, which is controlled very accurately by a regulated power supply incorporated in the instrument. An internal pressure sensor compensates for small changes in gas pressure to keep the readings stable. The CO&CO2&N2O sensor is based on dual-beam infra-red technology with full pressure and temperature correction. The module is exceptionally stable and requires virtually no maintenance or calibration. 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 analyzer is packed with features including fully programmable alarm circuits, programmable analogue outputs, easy calibration (any two or three user selectable gases), RS232 / RS485 communications, independent type K thermocouple and a full set of communications /data-logging software that is MS Excel compatible.
