    Mahoney CO2 Laser Power Probe Customer Reviews

    5.0 out of 5 stars.  A good CO2 power meter.  By A Y Van Heugten on July 14, 2014.  Very reliable. Less complex than a digital device, but does the job well. You have to wait a few minutes between readings, but that's a small price to pay for the the considerably lower cost of this item compared to digital meters.


    5.0 out of 5 stars. Does exactly what is supposed to. By danielvwnwieringen on July 7, 2014.  Does exactly what is supposed to. A great way to accurately line up the mirrors. Shipped and Received quickly.


    4.0 out of 5 stars. Differential temperature testing. By PatrickK on October 20, 2015.  Worked when used as directed, slightly tricky getting back to ambient temperature if using more than once using the "Cold water" technique as took a while to settle at new temperature. Adjustment quite stiff but overall gave good results.


    5.0 out of 5 stars. Must buy for novice user.  By P. Minke on July 30, 2014.  Simple, accurate and a must have for setting up and understanding the operation of CO2 laser. Especially if you bought a cheap Chinese model.


    5.0 out of 5 stars. Works great! Easy to use.  By James Graham on April 15, 2015.  Works great! Easy to use! Bought this to check out my 10 year old Epilog Helix 45, still running at 42 after 10 yrs.

  • Click for Video: Mahoney Laser Power Meter Probe Locating a Bad Mirror on a CO2 Laser Engraving/Cutting Machine.  

    The Mahoney laser power meter probe is utilized to locate bad optics. Maximum CO2 Laser output power is measured before and after each mirror. In this video, the final mirror is measured and found to be bad. The mirror absorbs roughly 9 percent of the laser energy. In general, mirrors are expected to absorb less than 3%.
