CG104

Extech CG104: Coating Thickness Tester

Measures the thickness of ferrous and non-ferrous substrates

The CG104 is a pocket-sized coating thickness tester that offers quick one-handed operation and non-destructive measurements of the thickness of ferrous and non-ferrous substrates. Its unique reversible display allows you to take readings in challenging angles of the area being measured, plus it has an easy-to-use menu system and backlit display feature. Built-in memory stores/recalls up to 255 readings. Complete with two AAA batteries, calibration standards (one ferrous plate, one non-ferrous plate, and one standard coating plate film), wrist strap, and soft case.
