Smart oxygen analyser

December 2002 Analytical Instrumentation & Environmental Monitoring

The WDGIV/IQ smart oxygen analyser from Ametek Thermox is a close-coupled extractive oxygen analyser that uses a zirconium oxide electrochemical cell for oxygen measurement. It is completely field serviceable, and all electronics are contained within the sensor. Set-up is simplified through a handheld or wall mount IQ link and RS485 communications are standard, or a Hart option is available.

With an operating range from 0,1-100% oxygen, the analyser has an output from 0-1% to 0-100% oxygen and an accuracy ±2% of measured value or ±0,1% oxygen, whichever is greater. The analyser has a 63% response of a process step change in less than three seconds.

High dewpoint sensors are available for sample dewpoints up to 370°C. The alarm can be set to oxygen, start of calibration, start of verify, or both. The WDGIV/IQ is EMC and safety compliant and offers simplified and lower installation costs. Ametek Thermox is represented locally by OEN Enterprises.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
