Illinois Instruments carries a complete line of O2 analysers to fit your application.  Our trace O2 Analysers have a measuring range of 0.1ppm up to 10,000ppm.  We also have percent O2 analysers with a measuring range of 0.1% to 100%.  We use two different types of sensor technologies in our O2 analysers, zirconia and fuel cell.  Applications for our O2 analysers include electronics, semiconductor, gas production, and metal heat-treating.

Our O2 Anlayzers can be configured in one of three ways.  The O2 analysers can be benchtop/panel mountable, NEMA 4X wall mountable, or 19 inch rack mountable.

Illinois Instruments' Series 900 O2 Analysers offer unmatched versatility in high performance on-line O2 analysers.

Utilizing a variety of specially engineered electrochemical fuel cells, the Series 900 O2 Analysers are 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 analyzer 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.
