  1. MSA Altair Review by Pappapig

    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. (Posted on 11/10/14)

  2. very well made detector Review by John D.

    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. (Posted on 5/5/14)

    It works like a charm
