Ultrasonic Thickness Gauge - QTG IV

The QTG IV Ultrasonic Thickness Gauge is the new and improved unit with A and B scan gauge, besides E-E (Thru-Paint) function. The instrument can measure with very high resolution (0.01 mm or 0.001 inches) the thickness of metallic and non-metallic materials such as steel, aluminum, titanium, plastics, ceramics, glass and any other good ultrasonic wave conductor. The QTG IV accurately displays readings in either inches or millimeters.

The QTG IV digital Ultrasonic Thickness Tester is a menu-driven, fully functional unit offering everything from the basic measurement to extended memory (10000 readings storage) and USB output capabilities. This dynamic gauge is designed to measure the thickness of metallic and non-metallic materials such as steel, aluminum, titanium, plastics, ceramics, glass and any other good ultrasonic wave conductor as long as it has parallel top and bottom surfaces. The QTG IV is a quite versatile model which can be easily equipped with any of the low & high frequency probes as well as a high temperature probe.
