Featuring an integrated diaphragm pump for precise localized sampling, a bright LCD for real-time multi-gas readouts, and simultaneous audio-visual-vibration alarms, it ensures maximum safety in industrial and hazardous environments. With rugged, water-resistant construction, 14-hour battery life, and smart data logging capabilities, it’s the trusted choice for millennial managers prioritizing workplace safety and compliance. ## Description The BW Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-gas detector with pump is a handheld, four-gas detector that uses an electrochemical cell sensor to monitor ambient H2S and carbon monoxide (CO), a capillary pore fuel cell to measure oxygen levels, and a catalytic bead sensor to monitor ambient combustible gases continuously. It has audio, visual, and vibration alarms, which alert simultaneously when gases reach any of four preset levels. The integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion. The detector has an alphanumeric LCD screen that shows real-time concentration of four monitored gases, the alarm type, the calibration requirements, the self-test pass or fail, and the battery life remaining. The LCD also displays a constant flashing heartbeat icon to indicate normal functioning. The detector is operated and adjusted with a single push button. It is used to indicate potentially harmful levels of gases naturally occurring in the environment; in a variety of occupational settings such as petroleum refineries, tanneries, sewage treatment facilities, and paper mills; and in other personal safety, educational, and ambient monitoring applications. This detector is set to alert to when gas levels reach any of four limits: a low-alarm level, indicating moderate danger; a high-alarm level, indicating significant danger; a short-term exposure limit (STEL), the maximum gas concentration to which workers can be exposed continuously for a short period of time without serious risk; and a time-weighted average (TWA) limit, the maximum average exposure that personnel can experience over an eight-hour work shift without serious risk. The 95 dB audible alarm sounds at different speeds to indicate the alarm type, and the three bright, wide-angled LED alarm bars and the built-in vibration alarm help alert the user to potentially dangerous levels of gases in high-noise conditions. The detector logs and retains data of the 10 most recent gas exposure events, which it can transmit via an infrared Datalink USB adapter to a personal computer (both sold separately). This product is powered by a replaceable AA alkaline battery that provides up to 14 hours of operational life. To ensure performance, the detector tests its sensor integrity, circuitry, and audible and visual alarms upon activation. It tests its battery upon activation and continuously during operation. The detector also features an automatic shutdown mode for additional safety, which activates when the detector fails its self-test. This detector comes with a back-mounted alligator clip to allow the unit to be worn on a belt, waistband, or lapel, and built in concussion-proof housing to help protect it against damage. It is water resistant, and is compatible with the BW Technologies MicroDock II automatic test system (sold separately). It has a European Conformity (CE) and ATEX certification in accordance with Directive 2004/108/EC for electromagnetic compatibility of electric and electronic equipment, and it is classified by Underwriters Laboratory (UL) to U.S. and Canadian standards as an Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, Division I, Group A, B, C , and D. It has an ingress protection (IP) rating of 66/67.SpecificationsGas TypesH2S, carbon monoxide (CO), oxygen (O2), Combustible Gases (%LEL)Measuring Range H2S: 0 to 200 ppmCO: 0 to 1,000 ppmO2: 0 to 30%Combustible: 0 to 100% LEL, 0 to 5% v/v Resolution H2: 1.0 ppmCO: 1.0 ppmO2: 0.1%Combustible: 1% LEL, 0.1% v/v Temperature Range-4 to +122 degree F/-20 to +50 degree C Humidity Range10% to 100% RH (non-condensing) Audible Alarm Sound Level95 dBDimensions5.1 x 3.2 x 1.9 inches/13.0 x 8.1 x 4.7 cm (H x W x D)*Weight11.92 oz./338 gBatteryAA alkaline with 14 hour life(at +68 to 122 degree F/+20 to 50 degree C)*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. A gas detector is a safety device that detects and monitors various toxic, combustible, and flammable gasses in an area, and which can also register a decrease in ambient oxygen. Gas detectors can be portable or stationary, and are typically classified by their detection methods, which include catalytic, electro-chemical, point infrared, open-path infrared, semiconductor, thermal path conductor, and paper tape detection. Gas detectors are first calibrated to known gasses that serve as a reference points. Their sensors can then be used to measure ambient gas concentrations in comparison to the calibration gasses. When gas concentrations exceed a pre-set limit, an alarm or signal is triggered, alerting the user to potential danger. Pre-set limits often include a low-alarm level, indicating a gas concentration that poses a moderate danger; a high-alarm level, indicating a gas concentration that poses a large danger; a short-term exposure limit (STEL), the maximum gas concentration to which workers can be exposed continuously for a short period of time without serious risk of harm, and time-weighted average (TWA) limit, the maximum average exposure personnel can experience over the course of an eight-hour work shift without serious risk of harm. Most gas detectors also feature LCD screens that provide a variety of information including gasses detected and their concentrations, pre-set exposure limits, and battery level. Gas detectors have a variety of industrial and governmental applications, such as in fire and rescue, mining, construction, petroleum refineries, tanneries, sewage treatment facilities, and paper mills. Portable gas detectors are typically used to monitor the air around personnel, are worn on clothing or on belts or harnesses, and are powered with rechargeable or disposable batteries. They generally require periodic calibration, testing, and battery recharging or replacement, although some fixed-life detectors are designed to perform for a number of years without calibration or battery replacement before being discarded. Stationary gas detectors are typically powered electrically and mounted near the process area of a plant or control room. They also require periodic service, testing, and calibration. BW Technologies by Honeywell manufactures and distributes portable and fixed gas monitoring equipment for use in a wide range of industries. The company, founded in 1987, is based in Canada in Calgary, Alberta. Review: Sniffs out the bad stuff - Bought these for work, to perform work in confined spaces. So far, they work perfect. We have them tested and calibrated often, and always hope that it will never have to go off, but it is nice knowing that something is keeping an eye out for ya.

So far, they work perfect. We have them tested and calibrated often, and always hope that it will never have to go off, but it is nice knowing that something is keeping an eye out for ya. ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on April 7, 2015* If you are looking for a great monitor you can count on, this is the one. ### ⭐⭐⭐ Not as happy as I should have been. *by T***L on May 16, 2025* This meter that was "like new" needed a H2S sensor before I could put this into service. Cost of purchase - $550.00, cost to replace the sensor - $ 140.00 This unit was only 8 months out of factory calibration. Not as happy as I should be with this purchase. Unit looks new and was delivered a bit late. Now my cost is about what the cost of new with a warranty :( ## Frequently Bought Together - BW Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-Gas Detector with Pump, Combustible, O2, H2S and CO, Yellow - BW Technologies GA-BXT Concussion Proof Rubber Boot with Stainless Steel Alligator Style Clip, for GasAlertMax XT II Detector - Replacement Oxygen Sensor for BW Tech Gas Alert Max XT II --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/2464440-gasalertmax-xt-ii-4-gas-detector-with-pump-combustible-o2](https://www.desertcart.hr/products/2464440-gasalertmax-xt-ii-4-gas-detector-with-pump-combustible-o2) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
