The GasAlert Max XT II portable multi-gas monitor for confined space workers is manufactured by the experienced team at BW Honeywell. Many years of gas detection technology and know-how have gone into this hand-held gas sniffer to make it BW's top of the line device for anyone needing to sample and monitor gas levels of enclosed spaces.

With an internal pump, the XT II allows anyone performing manhole entry (or similar work) to sample remote areas before entry (via the use of a sampling hose found in the Confined Space Kit).

Featuring four gas sensors, the GasAlert Max Detector can monitor hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2) and the lower explosive levels (%LEL) - a variety of dangerously combustible/flammable and explosive gases.

A large, bright LCD screen displays the levels of each gas present in the atmosphere, as well as battery levels and pump activity. The GasAlert Max XT II is one of the easiest ways to ensure on-site safety in the confined space industry.

Simple one-button operation - easily used by industrial workers wearing appropriate safety gloves - greatly reduces the training time for the end user while still allowing access to all the important information on this handheld gas monitor.

Three types of alerts provide a suitable alarm for all kinds of work environments: bright alert lights, a sonic alarm (95dB) and a vibration mode ensure that no matter where you are working, you will be alerted should any of the gases reach a dangerous level. On top of this, the GasAlert Max XT II sports a confidence beep that sounds at regular intervals, so you know that the monitor is functioning correctly.

These alerts can be tailored to your company's specific needs via the IR Connectivity Kit (part of the Confined Space Kit), which lets you adjust the Long Term Exposure Limits (LTW; ~8 hours), Short Term Exposure (STE) limits (5-15 minutes), as well as high/low levels for each gas.

All of this gas detection and sampling technology is built into this sturdy yet small device. It sports tough, concussion-proof housing which is IP66/67 rated for water-resistance, so you can be confident your investment in gas detection will last you for years to come.

Maintenance of the GasAlert Max from BW Technologies is a breeze: moisture and particle filters protect the sensors and can be easily monitored and changed via the built-in, easy-to-remove filter window.

The GasAlert Max XT II is fully compatible with the Micro Dock II which lets you retrieve data logs from each shift as well as adjust device settings and alert levels as needed. The tracking of gas levels, alerts and maintaining records of the OSHA standards is reliable and easy. The XT II is ideal for gas, sewer, oil rig or refinery workers, the armed services, mines or other confined space entry.

An optional accessory is the Confined Space Kit.

Also available as a separate item is the BW Calibration Gas.

Overall Rating?



  • We do have the GA-BXT concussion proof boot for the Max XT II available as a separate item. They are in stock.


  • Most likely you need a new Oxygen sensor. If the monitor has been dropped or wet that would do it too. If the monitor is brand new it could be a manufacturing defect. 95% of the time a new sensor fixes the problem.


  • Yes. The maximum length of hose for the Max XT II is 65 ft. Using a longer hose, allow about a second per foot for the air sample to reach the monitor.



  • The GasAlert Max XT II comes with the following:
    Wall charger
    Calibration certificate
    Manual (in hard copy and dvd)
    Screw driver
    5 replacement filters for the pump
    One replacement filter for the end of the hose
    One 3 ft. piece of clear hose with unit connector
    One 10 ft. piece of clear hose with unit connector


  • It sounds like there is a leak somewhere in between the pump inlet and the pump itself. First try replacing the filters if they are dirty the pump may be under too much strain. If replacing the filters doesn’t fix the problem it’s time to send the unit in for service. Here at PK Safety Supply we’re a factory authorized warranty repair center. Our typical turnaround time is just 24 hours and if the defect is covered under warranty it won’t cost you a penny! Please call today us to obtain an RMA.
