Introduction

ISM3
oxygen monitor The ISM is designed to measure oxygen concentration in a pure gas or
gas mixture of inert gas or CO2. The instrument is self contained and easy to install – just connect it to a pressurised tank or use the pump version of the ISM-3 to draw a sample from your process. The ISM uses a zirconia sensor, which provides very accurate a repeatable measurements without saturation over a long period of time.
The ISM-3 is highly accurate and yet simple to use. Typical applications for the ISM-3 are measuring purity levels from gas generators or measurement of the residual oxygen level in nitrogen fl ushing processes.
