The CG104 is a pocket-sized coating thickness tester that allows for quick one-handed operation and non-destructive thickness measurements on ferrous and non-ferrous surfaces. Its innovative reversible display allows you to capture readings from difficult angles of the area being measured, and it boasts an easy-to-use menu system and an illuminated display function. The built-in memory can store and remember up to 255 readings. Comes with two AAA batteries, calibration standards (one ferrous plate, one non-ferrous plate, and one standard coating plate sheet), wrist strap, and a protective box.
