Simple operation with pump. The rugged GasAlertMax XT reliably monitors up to four hazardous gases and combines simple one-button field operation with an integrated sampling pump.
User-adjustable options, which prevent foreign manipulation, allow the instrument to be customized to suit your applications.
Confined space entry and remote sampling have never been easier, with new smart pump technology.
Minimize pump blockages and improve the accuracy of remote sampling results. GasAlertMax XT is fully compatible with the MicroDock II automated calibration and test system.

• The continuous LCD display shows gas concentrations in real time.
• The compact and lightweight design makes it comfortable to wear.
• Waterproof.
• Simple and automatic calibration procedure; Compatible with BW's MicroDock II Automatic Calibration and Test Station.
• All-function self-diagnosis verifies * sensor, battery status, circuit integrity, and audible / visual alarms at startup.
