Quality is what you get when you purchase an MSA gas detector. These instruments are rugged and can truly withstand the abuses that a rough work environment can dish out. Not only are the instruments physically tough, but the electronics and sensors are equally rugged. MSA backs all of their instruments and sensors with an industry leading 3 year warranty. No short sensor life here. No sensors going dead at the moment you need them most. Calibration is simple and if you would like to automate the calibration and record keeping processes then the Galaxy Test Station is the ultimate accessory for you. User Friendly is another key feature. Simply turn the unit on and it is ready to use right out of the box, no huge user manual to wade through unless you need to make advanced changes to how the instrument operates.
If you are tired of other brands of gas detectors failing at the time you need them most, and if you want a monitor that you can trust your life with, then MSA should be your only choice. Whether you choose the Altair 4x, Altair 5X, Sirius, or Altair Single gas units you can be assured that you are getting the highest quality instrument in the industry.
