TQC ULTRASONIC THICKNESS GAUGE BASIC 

LD7015 

1

 

PRODUCT DESCRIPTION 

Ultrasonic thickness gauge specifically designed to measure the thickness of 
metallic and non-metallic materials e.g. aluminium, titanium, plastics, ceramics, 
glass and plastics. It can also be used to monitor all types of pipes and pressure 
vessels for loss of thickness due to corrosion or erosion. The gauge is easy to use 
and will give accurate readings to an accuracy of 1%. This unit is not suitable for 
cast iron due to its big crystalloid composition.
