The electrochemical technology, from our Series 900, is used in the oxygen trace analyser.  Our oxygen trace analyser, the Model 911, has a measuring range of 0.1ppm up to 10,000ppm. That means that this oxygen trace analyser is not affected by hydrocarbons.  Our oxygen trace analyser is frequently used by gas manufacturers to measure the quality of inert gases. 

Available options on our oxygen trace analyser include internal pumps, analog outputs, and alarms.  Mounting options on this oxygen trace analyser are benchtop/panel mount, NEMA 4X wall mount, or rack mount.

Illinois Instruments' Series 900 Oxygen Trace Analyser offers unmatched versatility in a high performance on-line oxygen trace analyser.

Utilizing a variety of specially engineered electrochemical fuel cells, the Series 900 Oxygen Trace Analyser is designed to monitor oxygen within most industrial gases and atmospheres. These highly advanced instruments incorporate user-friendly software and the highest quality sensors to provide accurate, reliable results.

No matter what your measuring range, the Series 900 has an analyser to suit your needs.

Trace Sensor (parts per million)
The trace sensor is designed for measuring 0-10,000 ppm oxygen in most industrial gas streams. This sensor, when used in a normal operating range, typically lasts 3-5 years.

Ultra-Low Trace Sensor (0-1 ppm)
This high performance sensor was developed for applications where continuous oxygen measurements are maintained between 0 and 1 ppm.

RACE™ Sensor
The RACE™ Sensor (USA and British patents pending) is a breakthrough in electrochemical technology. Our unique design prevents the sensor from being saturated by high levels of oxygen. With TURBOPURGE™, levels as low as 20 ppm can be reached from ambient air within 2 minutes. This sensor is unaffected by hydrocarbons or volatile atmospheres making it the ideal choice in applications such as wavesolder and reflow ovens.

The RACE™ Sensor is maintenance free and only requires infrequent calibration. No caustic electrolyte to monitor or replace. The RACE™ Sensor carries a 3 year warranty.

Percent Sensor
The Illinois Instruments percent sensor is capable of accurate measurements from 0 - 100% oxygen. Unlike most electrochemical sensors, this sensor is not affected by carbon dioxide.
