BW Technologies GasAlertMax XT II 4 Gas Detector %LEL, O2, H2S, CO Yellow


XT-XWHM-Y-NA GasAlertMax XT II 4 Gas Detector %LEL, O2, H2S, CO Yellow by BW Technologies

GasAlertMax XT II is the safest and most economical choice for multi-gas detection systems. Utilizing the most advanced technology on the market, the GasAlertMax accurately and reliably monitors up to four hazardous conditions, and offers a simple user friendly device for easy operation. Its standard safety features and compatibility with other instruments ensure that the gas detector is the best instrument for gas monitoring compliance.

GasAlertMax XT II specifications

The lightweight and portable unit is approximately 11.5 ounces, and features the latest technology allowing for a compact design. With an operational temperature range of -4 to 122 degrees Fahrenheit, the monitor is designed to function effectively in many harsh conditions. The cautionary yellow outer shell helps to ensure that the gas detector is carried with the user not left onsite. Additionally, the durable casing is resistant to water and features a built-in concussion proof boot.

Triple alarm system

The GasAlertMax XT II features a triple alarm system designed to alert users of potentially hazardous conditions. When the gas sensors detect specified levels of H2S, CO, O2, or combustible gases, the instrument will begin the triple alarm alert and notify users and those nearby. The device indicates these dangers with a vibrating alarm, an ultra bright visual alarm, and an audible alarm of over 95 decibels. The alarms are also designed to alert users of administrative needs such as battery replacement.

GasAlertMax XT II features

The GasAlertMax XT II has multi-language support features in English, French, Spanish, German, and Portuguese. The gas detector also has state of the art block detection with semi-conductor pressure sensor, and standard data and event logging. Accessories such as the belt holster, multi-unit cradle charger, and concussion proof boot are also available.

Upon activation, the unit will automatically test sensors, pumps, battery, and circuitry. For additional test and calibration, the GasAlertMax XT II is compatible with the MicroDock II automated test and calibration system and Fleet Manager II. Improving on its functionality, the unit is customizable. Users can change options for forced calibration and tests, safety locks, alarm setpoints, safe display mode, language choices, start-up message, and more.

The easy to read LCD screen displays continuous information about real-time gas concentrations and alarms. To maintain simplicity and ease of use, the GasAlertMax XT II also features a user and glove friendly one touch button for operation. The no-frills design has an added benefit of minimizing cost and user training. This simple, portable, and compact detector is the best instrument for confined spaces or potentially dangerous worksites.

Highest standards of reliability

The typical batter life ranges between 8 and 13 hours depending on the temperature. The durable and long lasting batteries can fully recharge in approximately 6 hours. The GasAlertMax XT II and its sensors feature a standard two year warranty. With safety and reliability as a top priority, BW Technologies has developed the multigas detector to utilize the most advanced technology on the market, while maintaining its simplicity and portability. When working in settings with possible gas exposure, users can be certain that the gas levels are being accurately and reliably monitored with the best technology available.

The monitor displays Bump Test Now and alarms. How do you pass through this and begin monitoring. This came calibrated from factory
1 Answer

Hi Scott,

Thank you for your question.   If the bump check feature is turned on then you will need to attach your calibration gas when it prompts you for the bump check and then the instrument will need to pass the bump check in order to proceed to the normal readings screen.

Does this unit require a full calibration by the mfg. company or the user company. And if so what is the interval. I am not talking about the bump test.
1 Answer
Hello, The GasAlertMax XT ii comes fully calibrated from the factory. The calibration interval is set to 180 days by default. After this time the instrument would need a full calibration once it reaches the 180 day limit. This can be done by either purchasing calibration gas and regulator, p/n#'s cg-q34-4 and Reg-0.5, or sending in to us for calibration by starting a work order here https://www.jjstech.com/services.html.

I have the Gas Alert Max XTII and I was wondering if the sensors have an accuracy + / - range? If so what are they? Thank you
1 Answer
The sensors have an accuracy of +- 5% generally. This is based on the gas used to calibrate (CO: 100 PPM, H2S: 25 PPM, LEL: 50%LEL, O2: 18.0%/vol). Ranges are as follows. CO: 0-500 PPM H2S: 0-100 PPM LEL: 0-100% LEL (not %/vol) O2: 0-30%/vol

from CA asked:

I just changed my Oxygen sensor and it fails to Auto-Zero and reads about 26%. How do I get the new sensor to work?
2 Answers
Hello, Whenever a new oxygen sensor is installed into an instrument you need to let it sit for approximately 20 minutes before turning it on and calibrating it. The reason for this is that since the sensor is detecting oxygen in the atmosphere but is not in the circuit, the charge has nowhere to go, and builds up in the sensor. Therefore when you install it into the instrument the built up charge is now released from the sensor, and this is what causes the high readings until the excess charge is dissipated from the sensor.
Submitted by: Joe Spratley on April 5, 2018
All sensors (oxygen especially) require a stabilization period when they are installed. Oxygen sensors have built up a signal prior to plugging them in to that sensor port. After installing a new one, put the monitor back together and wait about an hour. Then turn it on and calibrate it. The sensor should be stable and respond to gas properly.
