Infrared Gas Monitor

Edinburgh Sensor’s Gas Monitor range offers high accuracy for the detection and measurement of gases. The Guardian NG Infrared Gas Monitor supplied by Edinburgh Sensors offers near-analyser quality, continuous sampling, measurement and display of target gas concentrations.

What does a Gas Monitor Detect?

The ‘Guardian NG’ gas monitor provides high accuracy detection and measurement of either CO₂or CH₄gases, where detection level ranges of between 0 – 3000ppm and 0 – 100% by volume are required. The equipment is used for single gas measurement at a time.
