Multi-Technology Oxygen Sensor

Multi-Technology Oxygen Sensor – Overview

This wall-mounted instrument is designed to measure the oxygen concentration in inert gas supplied under positive pressure. This analyser utilises zirconia or electrochemical technology to give a reliable solution for the measurement of % and ppm oxygen ranges. The zirconia sensor life is typically 3 to 5 years when used within stated specifications. It has fast response times and a long service life. The electrochemical sensor allows for the measurement of background gases containing hydrocarbons. It has virtually no drift, ensuring your measurements are always accurate. It also has integrated audible-visual alarms that you can configure, and is available with multiple measurement ranges to customise your setup.
