Range 0.040 - 8.000 inches
Ultrasonic thickness gauges use sound wave to measure wall thickness. Different types of materials have different inherent acoustic velocities. ( sound travels at different speeds through different materials ).For example the acoustic velocity of steel is 0.2330 inches/microsecond and that of aluminium is 0.2500 inches/microsecond. The TI 45 can be set to any acoustic velocity depending on the material being measured. The instruction book includes a table of acoustic velocities for common materials. Even if you don't know the acoustic velocity or your material you can measure it with the TI45 provided you have a sample of material of known thickness to start with.
