Ultrasonic Thickness Gauges

DeFelsko Ultrasonic Thickness Gauge UTG Overview

Ultrasonic Thickness Gauges

Ultrasonic Thickness Gauges like the DeFelsko PosiTector UTG Gauge measures the wall thickness of materials such as steel, plastic and more. Ideal for measuring the effects of corrosion or erosion on tanks, pipes or any structure where access is limited to one side. Multiple echo (ME) Thru-Paint models measure the metal thickness of a painted structure without having to remove the coating.
