    Can the battery be changed or does the entire unit get thrown away when the battery dies?

    Edit: This is a 2 year disposable maintenance free H2S monitor. The battery cannot be replaced and the display does not show PPM level of H2S. It has a low alarm setting at 10ppm and a high alarm setting at 15ppm. The monitor lasts 2 years or produces 1,080 minutes (18 hrs) of alarm under normal conditions.

    Purchased this H2S monitor at a substantial savings from my last one. I like this brand, as it has a record of durability.
    Wishing you continued success.

    MSA Altair

    Posted by Pappapig on Nov 10th 2014

    I have been using H2S detectors for over 30 years. I bought an MSA Altair 24 months ago and am very happy with it. Most in the past were the BW brand and I never had one last the entire time it was supposed to.

    very well made detector

    Posted by John D. on May 5th 2014

    This appears to be a very well made detector, but the fault is my own in
    that I thought I was buying a detector that would be showing me the current
    levels and not just a warning when the level got dangerous.
