The LY-985V coating thickness gauge, our patented product, is specifically designed for non-destructively measuring coating thickness on circular workpieces with diameters up to 100mm, capable of measuring both non-magnetic coatings (e.g., aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic substrates (e.g., steel, iron, alloys, hard magnetic steel, etc.) and non-conductive coatings (e.g., enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (e.g., copper, aluminum, zinc, tin, etc.).

1. Features

* Spring-guided probe with ultra-wear-resistant alloy tip ensures consistent contact pressure and stable measurement accuracy even on hard or rough surfaces, with a durability exceeding 500,000 measurements.
* High speed: 0.3 seconds per measurement.

* High accuracy and stability, capable of measuring ultra-thin coatings (1-5 μm).

* Supports hot-swappable interchange of multiple probe types.

* Wide measurement range with high resolution.

* Light-contact measurement achieves reliable precision.

* Automatic substrate recognition(Fe/ NFe).

* Split-type design, facilitating measurements in narrow areas.

*Four display modes: Readings Only, Readings& Statistics, Readings& Bar Graph, Readings& Run Chart.

* Statistical functions: Average (x̄), Max/Min, Standard Deviation (σ), Count (N).

* Four calibration modes: Zero Calibration, One Point Calibration, Two Point Calibration, Five Point Calibration.

* HD color screen with auto-rotation for multi-angle viewing.

* Supports USB connection to PCs for data acquisition and automated report generation, facilitating efficient corporate data management.

* Large storage capacity: 16 groups, 100 data points per group (total 1,600).

* Upper/lower limit alarms.
