The PTG Series of precision ultrasonic thickness gages are ideal for measuring wall thickness for manufactured parts requiring unprecedented accuracy and resolution. The PTG Series utilizes single element transducers and offers a 30 MHz, square wave pulser, 0.0001” or 1micron resolution with the ability to store and re-call 30 unique applications. So if you are measuring light bulbs, plastic bottles, golf clubs, coil steel, thin aluminum, aircraft parts and even pure gold bars, the PTG Series is the right choice.
