SKU: CG204
The Extech CG204 is a portable meter designed for non-invasive coating thickness measurements with automatic recognition of ferrous and non-ferrous substrates. The tester uses dual technology to indicate ferrous (magnetic induction measurement) and non-ferrous (eddy current measurement) substrates. It features single and continuous measurement modes as well as direct and group working modes, 400-reading memory storage, and user-programmable high/low alarms. The CG204 comes with two AAA batteries, USB cable, software, calibration iron, calibration aluminum, precision standards, pouch case, and user manual.

The CG104 is a pocket-sized coating thickness tester which 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 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.

Dual technology provides automatic recognition for ferrous and non-ferrous substrates without having you guess the material. Allows for quick, one-handed operation, non- destructive measurement of the coating thickness on various surfaces.

The Extech CG304 Coating Thickness Tester offers a non-destructive way of measuring the thickness of ferrous and non-ferrous substrates with automatic recognition of the material being measured. Memory stores 2500 readings. The unique Bluetooth interface feature wirelessly transmits data to your PC for further analysis and enables you to generate a documented report. Special LCD with backlight feature and contrast for easy viewing in various lighting conditions. Complete with two AAA batteries, software, hard case, steel and aluminum substrates, and standard films for calibration.

The Extech TKG100 offers Thickness Gauges designed in compact, handheld, rugged housing ideal for field use. The ultrasonic technology allows for non-destructive thickness measurements for primarily steel structures. It includes multiple transducer options for high temperature and difficult to measure materials. Complete with 2oz bottle of coolant, 2 AA batteries, 5 MHz Transducer, and hard carrying case.
