The KD-920S is a high-precision 2-in-1 coating thickness tester combining magnetic induction and eddy current principles. It measures coatings on magnetic (steel) and non-magnetic (aluminum) substrates with 0.1μm resolution, supporting ranges up to 2000μm (magnetic) and 1500μm (eddy current). The device features a color LCD display, auto temperature compensation, and data storage for 500 readings. With a compact design (240g) and battery operation, it is ideal for lab and field use in automotive, aerospace, and surface treatment industries.

• 2-in-1 measurement: magnetic (ferrous) and eddy current (non-ferrous) modes in one device.
• High resolution of 0.1μm for precise coating thickness detection.
• Auto temperature compensation corrects for environmental and probe temperature drift.
• Three measurement modes: high-precision averaging, real-time scan, and single-point.
• Five statistical functions: MEAN, MAX, MIN, NO., and S.DEV for data analysis.
• Zero-point, single-point, and two-point calibration options for accuracy.
• Data storage for 500 readings with delete and alarm functions for out-of-range values.
• Three power-saving modes: manual, auto-shutoff, and low-battery auto-power off.
• Audible beep feedback for measurement confirmation and operation.
• Compact, lightweight design (240g) for easy one-handed operation.
