Dakota Ultrasonics MX-1

Preset Velocity Thickness Gauge


This item has been discontinued, click on the link for the alternative - ZX-1

The MX-1 is a simple, fixed velocity gauge.

The advantages of a fixed velocity gauge include:

  • No calibration, just Probe Zero and you are ready to test.
  • Less expensive, hundreds of dollars less than other gauges.
  • No special training, instrument is always calibrated for selected materials.
  • No calibration block required

    The MX-1 will hold a single velocity, making it the perfect choice for applications, where only one material is being tested day after day. With the preset velocity in the gauge, you simply turn it on and go to work. The velocity is set in the MX-1 with a simple software program that is supplied with the unit. The tool's backlit display is easy to read, even in dim light conditions and the unit operates for up to 80 hours on alkaline batteries and 20 hours on NiCad. The MX-1 is packaged in an all metal case, sealed with gaskets to protect it from harsh working environments. The MX-1 comes complete, ready to use and is protected by Dakota Ultrasonics 5 year limited warranty.
