Digital Ultrasonic Thickness Meter to measure 1 ~ 300mm with user-friendly menu interface and type C charging

  • User friendly menu operation with dot matrix display
  • DC 5V/1A type C charging with 2000mAh battery
  • Memory storage with each set of measured value, sound velocity, max, min and avg value. 
  • Measure material sound velocity using 1 point calibration
  • Option for silent operation and auto power off for conserving battery. 

Applicable to measure the thickness of many materials, like steel, cast iron, aluminium, red copper, brass, zinc, quartz glass, polyethylene, PVC, gray cast iron, nodular cast iron. It is widely used in almost all kinds of industries.

Measuring principle:

Ultrasonic thickness gauge determines the sample thickness by measuring the amount of time it takes for a sound pulse, generated by an ultrasonic transducer, to travel through a test piece and reflect from the inside surface or a far wall.

Measuring range as per #45 Steel

Every material has its own sound velocity, by which the sound propagates through that medium. For accurate thickness readings, the exact sound velocity has to be set before measuring. A few velocities for materials is already preset as below:
