Measures the Oxygen content in inert gasses from 1 ppm to 100%

The Industrial Sensor Module ISM-3 is a digitally controlled O2 analyser with user programmable gas alarms and complete, self-diagnostics with system alarms.

An extremely versatile analyser with very low maintenance requirements and high reliability. Ideal for high precision welding applications.

ISM-3i & ISM-3x are both available with or without an integral sample pump. There are two different display options to suit the application.

  • ISM-3i – separate panel mounted display
  • ISM-3x – integrated display within an enclosure

Proven technology with excellent accuracy of better than +/- 1% of the reading. A large measuring range of 1ppm – 100% O2 auto-ranging. Two settable oxygen % alarms.
