Multi-gas made easier
The easy to wear, slim and compact GasAlertMicroClip 
provides affordable protection from atmospheric gas 
hazards. For standard operation with features you can 
count on, opt for the GasAlertMicroClip XT. For extended 
battery life, especially in cold weather, choose the 
GasAlertMicroClip XL. Both offer visual compliance at a 
glance with the flashing, green IntelliFlash™. Easy one-
button operation reduces training time and lets workers 
focus on the job at hand. For simple, cost-effective 
management of your records, calibration and bump 
testing, choose BW’s MicroDock II automatic test and 
calibration system and Fleet Manager II software.
