Linshang LS221 Split-Probe Coating Thickness Gauge

The Linshang LS221 is a split-probe coating thickness gauge for industrial measurement on ferrous and non-ferrous metal substrates. Its external cable probe separates the measurement point from the display, making it easier to inspect confined spaces, recessed components and locations where an integrated handheld gauge is difficult to position or read.

Hall-effect and eddy-current measurement support non-magnetic coatings on ferrous metals and non-conductive coatings on aluminum, copper, zinc and other non-ferrous metals. The 0–5000μm range addresses paint, powder coating, plating, anodized layers and other industrial surface treatments.

Key Features

• External cable probe: Reach narrow, recessed or visually obstructed measurement locations while keeping the display accessible.
• 0–5000μm measuring range: Covers thin surface finishes and thicker industrial coating systems.
• Automatic Fe/NFe recognition: Identifies ferrous and non-ferrous substrates and selects the corresponding measurement method.
• Three measurement modes: Select Fe, NFe or automatic Fe/NFe operation according to the inspection task.
• Hall-effect measurement: Measures non-magnetic coatings such as paint, powder coating and zinc on ferrous substrates.
• Eddy-current measurement: Measures non-conductive coatings on aluminum, copper, zinc and other non-ferrous metals.
• 0.5s response: Supports efficient spot checks across production parts and installed structures.
• Digital probe technology: Improves zero stability and reduces susceptibility to signal interference.
• Wear-resistant ruby probe: Supports frequent measurement with reduced tip abrasion.
• Temperature compensation: Helps maintain stable measurement behavior as environmental conditions change.
• Negative-value display: Helps verify zero adjustment before beginning an inspection sequence.
• Portable operation: Uses two replaceable AAA batteries for laboratory and field inspection.

Applications

• Metal processing and fabrication
• Industrial painting and powder coating
• Hardware and cabinet inspection
• Shipbuilding and marine coatings
• Aerospace component inspection
• Anodized aluminum measurement
• Confined or difficult-access measurement points

Why Choose the Linshang LS221?

Choose the LS221 for industrial coating inspection where probe access is more important than automotive repair-identification functions. Its split-probe design reaches confined locations, while Fe/NFe measurement supports a wider range of metal-processing, coating, shipbuilding and aerospace applications.
