Description GasAlertMax XT II
GasAlertMax XT II Gas detector, with pump is a series of portable gas detectors that can simultaneously measure 4 types of CO, H2S, O2 and explosive gas according to %LEL. Compact when used at the scene, the GasAlertMax XT II gas detector is integrated with an internal sampling pump. Designed for stable, reliable and easy-to-use operation. SmartSample enhances remote sampling for the most accurate results.
Simple to use interface with just 1 button, easy to use when using gloves, users can change the options to suit the specific use. Confined space can be purchased for the convenience of off-field use or an additional MicroDock II set for automatic machine calibration and inspection.
