Illinois Instruments offers an entire line of process analyzer for testing oxygen, moisture, and carbon dioxide.  Incorporated in 1986, Illinois Instruments built its roots in the process analyzer market.  Within a few years, we developed a line of headspace analyzers, and have now grown to add oxygen permeation and water vapor transmission analyzers.

The process analyzer market consists of end users and OEMs (Original Equipment Manufacturers) alike.  Applications for our process analyzer include semiconductor, gas manufacturing, electronics assembly, and food packaging.  As a proven leader in the process analyzer market, Illinois Instruments is committed to supplying you with a process analyzer to meet your specific application.

Illinois Instruments' Series 900 Process Analyzer offers unmatched versatility in a high performance on-line process analyzer.

Utilizing a variety of specially engineered electrochemical fuel cells, the Series 900 Process Analyzer 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 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.
