General introduction:
- The XT-XWHM-Y-OE gas detector is one of the models of the GaxAlertmax XT II Series, manufactured by BW Technologies Canada, one of the members of the Honeywell family.
- The machine is designed to measure up to 4 gases: Explosive gas according to %LEL, Oxygen, CO and H2S, in the GaxAlertmax XT II series can optionally measure 3 gases or 2 gases by configuring the sensor attached in itself. The machine sets the highest level of explosion protection standards – intrinsically safety, suitable for all industries such as: Ship, Petrochemical, Environment …

Detailed review:
- On the surface, the machine is quite compact compared to multi-gas detectors, holding on to the hand feels very strong, the machine is equipped with a yellow impact-resistant rubber case (black option – a little more expensive). It is equipped with a large LCD screen, with 3 LEDs (the lights will glow differently when the device detects different gas concentrations, this type of single-type glow is called IntelliFlash), a siren and only one push button for all functions. This one-button model is also very convenient to use when wearing gloves. In addition, the front of the machine has a screw, when opening this cover will reveal 4 gas sensors below. Once this lid is opened, the machine automatically turns off the pump and switches to diffusion-type gas measurement mode.

- The back of the machine is an air suction port with a dust filter, the machine is equipped with a built-in suction pump inside the machine, as introduced by the company, this is a diaphragm pump type, the pump capacity can suck air at a distance of over 20m, which serves a very important function of checking the tank , safe, work area before going in person. On the back is also equipped with a clamp with a belt that is very convenient for free work. The charging foot is designed quite meticulously, with this choke leg ensuring complete isolation inside and outside the machine, in addition, besides the choke legs integrated with the infrared connector – using the download of measured data to the computer or installing a gas detector through the software.
