PCE Instruments TG 250 Ultrasonic Thickness Gauge 1 to 250 mm

Model # TG 250

PCE-TG 250 is a portable Thickness Meter with an easy-to-read 4-digit display. This ultrasound-based Thickness Meter uses a contact transducer (included) to measure the thickness of coated and uncoated ferrous and non-ferrous metal, glass, plastic, and other homogeneous materials including aluminum, brass, copper, iron, lead, nickel, steel, gold, titanium, pyrex and quartz glass, nylon, polyethylene, and silicone rubber.
