Product Details
KMC-666 Digital Car Paint Thickness Gauge
Product Introduction
The KMC-666 Digital Paint Thickness Gauge is a portable,
battery-operated instrument designed for non-destructive
measurement of coating thickness on metal surfaces. With 2.5%
accuracy and automatic substrate detection, it efficiently
identifies paint, galvanized layers, and other coatings on ferrous
and non-ferrous metals, making it essential for automotive
inspection, manufacturing quality control, and maintenance.
Product Features
Dual-Substrate Measurement:
Automatically identifies ferrous (Fe) and non-ferrous (NFe)
substrates using magnetic induction and eddy current principles.
High Accuracy:
±2.5% full-scale accuracy for precise coating thickness readings
(0–2000μm range).
Environmental Adaptability:
Operates in -20–50°C (-4–122°F), resistant to electrostatic
interference and moisture.
User-Friendly Design:
Compact 114×53×25mm size, 80g weight for handheld use; auto-shutoff
to conserve battery life.
