Topinst TG 50 is a portable ultrasonic tester or ultrasonic thickness gauge with an easy-to-read 4-digit display. This ultrasound-based thickness meter uses a contact transducer (included) to measure the thickness of metal, glass and homogeneous plastic including steel, cast iron, aluminum, copper, brass, zinc, quartz glass, PE, PVC, grey cast iron and ductile iron.

Before beginning the measurement process, it is essential that you choose the type of material to be measured from the device menu. See user manual for material codes. Select your desired unit of measurement (mm / inch). Make sure the transducer is connected properly to the device. If so, the display will show “((•))”. Put some contact paste or gel on the material you wish to measure and press the transducer head on the gel. The thickness measurement data will appear on the display and remain on the display until a new measurement is made or the device is powered off.

See accessories for high-temperature, miniature and replacement transducer, contact gel, PC software and ISO calibration options.
