Hardness Tester
Ultrasonic Thickness gauge



The QS5 DL features a material condition analyzer, B-Scan graphics, a coupling level indicator, and it also includes a Data Logger to transfer readings stored in the unit memory to a PC using dmq DataCenter software included at no charge.

Measure tubes, pipes, storage tanks, valves, pressured recipients, boilers, naval hulls, and just about any metal parts or structures with accurate results. Other materials such as plastics, acrylics, ceramics, and glass can also be measured.
