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

  • User friendly menu operation. 
  • Adjustable backlight LCD. 
  • Memory storage with each set of measured value, sound velocity, max, min and avg value. 
  • 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.
