BW-GAMXTII Honeywell BW GasAlert Max XT II 4-Gas Portable Gas DetectorThe Honeywell BW GasAlert Max XT II utilizes 4 sensor technologies for gas monitoring in confined spaces. The GasAlert Max XT II detects oxygen (0-30% O2), carbon monoxide (0-1000 ppm CO), hydrogen sulfide (0-200 ppm H2S) and combustibles (0-100% LEL). A simple one-button operation reduces training time and prevents operator error. Audible, visual, and vibrating alarms warn of potentially hazardous conditions.The BW GasAlert Max XT II has a light and compact design for wearing comfortably. The case is water-resistant, and is surrounded by a concussion-proof rubberized boot with a built-in alligator clip. This monitor provides continuous visual confirmation of detector operation.FeaturesConfined Space detection for O2, CO, H2S, and Combustibles (LEL 0-100%)Continuous LCD shows real-time concentrationsCompact, lightweight, and easy to wearSimple automatic calibration procedure10 hr battery life - recharges in 6 hoursIntegrated sampling pumpOne-button operation reduces training timeAudible, visual, and vibrating alarmsBuilt-in concussion boot and alligator clip
