The Guardian NG analyzers are fast accurate and reliable infrared gas monitors offering continuous sampling, high accuracy, and display of target gas concentrations.

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

Our Guardian instruments are easy-to-install, stand-alone products that require minimum setup. The Guardian is supplied with LCD and digital alarm set-point controls, housed in a robust plastic IP54-rated enclosure to prevent the ingress of particulates and water.
