Coating Thickness Gauge for Metal Surfaces Autool TG501

Country of origin: China, warranty period - 24 months

AUTOOL TG501 is a precise coating thickness gauge designed to measure coating thickness on ferrous (Fe) and non-ferrous (NFe) surfaces. The device features a high-resolution sensor, automatic substrate recognition, screen auto-rotation, and power-saving auto shut-off. The package includes calibration foils and a metal substrate, and multi-unit measurement support ensures versatile application in automotive, industrial, or quality control fields.

Functions:

• High-precision sensor measures from 0 to 2000 μm, with accuracy up to 0.1 μm
• Automatic substrate type (Fe/NFe) recognition
• Auto screen rotation – convenient in complex situations
• Auto shut-off after 2 minutes of inactivity
• Includes calibration metal substrate and thickness foil
• Selectable measurement units: μm, mm, mil
