The Guardian range of infrared gas monitors offers near-analyser quality continuous sampling, measurement and display of target gas concentrations at a very attractive cost.

The ‘Guardian Plus’ range provides high accuracy detection and measurement of either CO2 or CH4 gases, where detection level ranges of between 0-3000ppm and 0-100% by volume are required.

Suitable for a wide variety of applications these wall-mounted monitors can detect gases from sampling points up to 30 metres away, using the integral sampling system.

The proven reputation of these instruments for reliability, accuracy and long-term stability with low maintenance requirements can be attributed to our proprietary dual-wavelength infrared sensor technology and over thirty years of sensor design and manufacturing experience.
