In-process O2 and temperature measurement in environments up to 650 °C
RAPIDOX 2100
Zirconia oxygen analyser with remote sensor
Trace-level oxygen analysis with the sensor placed directly in the process, up to 25 m away.
A sensor made for harsh processes
The analyser works with a rugged, long-life zirconia sensor on a remote cable, paired with a type K thermocouple, so oxygen and temperature are measured directly in the sample gas. Analysis is fast and accurate down to the low ppm range in environments up to 650 °C.
Zirconia technology suits inert atmospheres in aggressive industrial processes, including high-temperature locations and vacuum. Where it is unsuitable — high oxygen levels or samples with VOC, flammable gases, CO, H2 or He — an electrochemical sensor is fitted instead, with ranges of 1 ppm to 1 % or up to 100 % O2.
Main features
- Remote sensor manifold, up to 25 m with optional extension cables.
- Two fully programmable high/low alarm relays.
- Programmable analogue outputs and digital communications.
- Windows software with live graphing and Excel-compatible data logging.
- Operates on any worldwide mains voltage (90-260 V AC); password protection.
- Panel-mount, wall-mount IP65 or OEM configurations.
Configuration, applications and accessories
Multiple measurements in one instrument
Besides the standard type K thermocouple, optional auxiliary pressure, vacuum and dewpoint sensors can be connected, and a printer can be attached via the serial port for permanent records. For integration into a product or process the analyser is available as an OEM solution; it complies with EMC Directive 2004/108/EC and carries UL/ETL certification UL-61010-1.
