Features: Basic function: allows quick and accurate measurement of the thickness of non-metallic coatings (e.g. paints, films, etc.) on the surface of metallic substrates. Dual automotive/user mode: You can measure the coating thickness of the substrate material for calibration purposes. AutomotiveThe automotive mode can be used without calibration to measure the coating thickness of substrate materials such as iron, aluminium and zinc, and is suitable for automotive thickness measurement. 3 measurement modes can be switched: single measurement (SNG), continuous measurement (CTN) and differential measurement (DIF) are selectable and can be easily switched by pressing the MODE key. Three types of calibration in user mode: including zero calibration, two-point calibration and basic calibration.Metric and imperial measurement units: a short press on the UNIT button switches between mm (metric) and mil (imperial).
