Starrett Ultrasonic Thickness Tester with LCD Display - 0.040-12.0" Range, Velocity Adjustment, 20 Group Memory - 3812

The Starrett Ultrasonic Thickness Tester is a highly accurate, menu-driven device engineered to measure material thickness across a wide range of metallic and non-metallic surfaces. With a 0.040" to 12.0" range and precision accuracy of ±(0.5% thickness + .001"), it is ideal for inspecting aluminum, titanium, plastic, ceramic, glass, and other materials with parallel surfaces. The unit features an easy-to-read LCD display, sound velocity calibration, and can switch between inch and millimeter units. Its internal memory stores up to 2,000 readings across 20 memory groups, making it perfect for repetitive testing and long-term projects. Operating in temperatures from 32-DegreeF to 122-DegreeF and powered by two 3V AA batteries, the 3812 is designed for portability and long-lasting performance in the lab or field.
