Process oxygen analysers withstand hydrogen

Edited by the Processingtalk editorial team May 13, 2003

The Systech Series 900 On-Line Oxygen Analysers are designed to monitor the oxygen content of most industrial gases including hydrogen, gases containing combustibles, hydrocarbons and inert gases

The Series 900 analysers incorporate advanced, user-friendly software to provide a combination of ease of use and accurate and reliable results.

Using a range of electrochemical fuel cells, the Series 900 analyser eliminates compromise by allowing an exact match of sensor to each application.

Four long life, maintenance free sensors are available to cover the range of oxygen content from 0.01 ppm to 100%.

Designed for continuous on-line applications, the Series 900 is virtually maintenance free, with programmable, timed auto-calibration to any oxygen level using ambient air or, for ISO purposes, a certified, traceable gas to meet the most demanding quality assurance regimes.

The analysers are insensitive to sample flow rate and unaffected by vibration or position.

The rapid response and the large, auto-ranging LED display make the analysers especially easy to use and the provision of analogue outputs, high/low and fault alarms plus RS232/485 communications make the Series 900 especially suitable for process control, remote monitoring and charting applications.

Choices of sampling systems in brass/copper or stainless steel allow the installation to be matched to each application.

The four electrochemical sensors are: Ultra-Low Trace, 0-1 ppm, Trace, 0.1 ppm-1%, Race, 0.1 ppm-30% and Percent, 0-100%.

The Race sensor is a patented design that prevents the sensor becoming saturated by high levels of oxygen.

The Turbopurge facility allows levels as low as 20 ppm to be reached from ambient air within two minutes.

This sensor is unaffected by hydrocarbons or volatile atmospheres such as found in wave solder and reflow ovens.

The Systech Series 900 On-line Oxygen Analysers, available in 19 inch rack mount, panel/bench and NEMA 4X/IP66 water and weatherproof configurations, provide the highest levels of accuracy, reliability and flexibility under the most demanding industrial operation conditions.

Systech Instruments is one of the world's leading designers and manufacturers of gas analysis instrumentation and has agents and distributors in most major countries.

Systech gas analysis equipment is an essential part of the production process in many industries, including industrial gases, petrochemicals, pharmaceuticals, electronics and food, and is widely used by university and industrial research facilities.
