The versatile TKG Series of ultrasonic thickness gauges use ultrasonic technology to capture nondestructive thickness measurements on various engineered materials, typically to measure wall thicknesses in steel structures where only one side is accessible. TKG gauges are also used to measure thicknesses on metal components found on aircraft sections, ship hulls and marine systems. These gauges measure a wide thickness range (0.040-20 inches), quickly display thickness values and offer visual and audible alerts. They offer one-handed controls, intuitive interface and an easy-to-read LC D display.
