Hardness Tester
Ultrasonic Thickness gauge



The QS5 DLE is the most complete model in the QS5 Series. It features Multi-Echo capabilities and a Data Logger so that data stored in the unit memory (32000 readings) can be sent to PC using dmq DataCenter software included at no additional charge.

Measure painted metal parts such as tubes, pipes, storage tanks, boilers and naval hulls without having to remove the paint and in Pulse-Echo mode (regular measurements) other materials such as plastics, acrylics, ceramics and glass can also be measured.
