- Zero-point calibration: Calibrate the instrument to improve test accuracy and ensure higher precision readings. - Statistical display: The device shows mean, minimum, maximum, and count for quick data review. - Multifunction design: Battery level indicator and automatic shutoff after 3 minutes of inactivity; backlight on/off control for visibility in different lighting. - Easy operation: Built-in magnetic induction and dual-principle probe automatically identify the measured metal substrate; simply place on the surface to automatically calculate coating thickness. - Use scenarios: - Automotive coating checks: verify paint thickness on body panels and joints to ensure uniform protection. - Industrial maintenance: measure coating thickness on ferrous and non-ferrous surfaces of machinery, pipelines, and structural components. - Quality control in fabrication: quickly assess coating consistency on metal parts during production with automatic substrate identification.
