Economy Ultrasonic Wall Thickness Gauge

Wall Thickness Gauge Model TI-45 Economy Unit
The TI-45 ultrasonic wall thickness gauge accurately measures wall thickness and corrosion of all metal, ceramics glass and most rigid plastics. The probe's unique spring loaded centering shell permits measurements on a variety of surfaces including cylindrical parts.
  • Wall thickness on hard materials including corrosion of tank walls, piping and hull plates
  • Inspection of metals including steel, cast iron ( malleable, and spheroidal graphite ), aluminium, copper, brass, titanium, sheet metal, storage tanks, ships, structures and piping systems.
  • Inspection of non-metals including glass, ceramics and hard plastics (except acrylic resin)
  • Direct readout of thickness inches or mm
  • Built in test plate
  • Calibrate for a wide range of rigid materials
  • Acoustic velocity table for common materials included

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.
