Range, principle, power supply, probe — we break instrument selection down into questions you can actually answer. Includes a US market price-structure analysis and a pre-purchase checklist.
The correct order is: substrate material → coating type → thickness range → working environment → accuracy requirement → data capability → compliance and certificates. Skipping the first step can…
Range selection follows the “typical thickness in the 20%-80% band” rule. Common coating-thickness bands are 0-1250μm (thin coatings and anodising), 0-2000μm (general industrial), 0-3000/5000μm (high-build and pipeline anti-corrosion), 0-6000/10000μm (heavy…
Dry-battery models are low cost, replaceable on site and suit low frequency and remote work; built-in Li-ion models need no replacement and suit high-frequency production lines and situations needing stable…
The US coating-thickness gauge market is two-tier: the DIY tier clusters at $18-250, the professional industrial tier starts at $740 and rises to several thousand dollars, and the $250-740 middle…
Ultrasonic thickness gauges divide by capability into four classes: general-purpose covers routine wall thickness, wide-range covers thick walls and high accuracy, coating-penetrating covers painted workpieces without grinding, and ultra-thin single-crystal…
For coatings on concrete and cement-mortar surfaces choose DR200A (40-1200μm); for coatings on wood, plastic and glass surfaces choose DR200B (18-1000μm, with a small probe). Both share the main-unit platform…
Transmittance meters split by form into split portable (suited to vehicle windows and field measurement), benchtop (suited to lenses and small workpieces) and tri-path-optics models (covering visible, blue-violet and other…
Gloss is a relative quantity and must be compared at the same incidence angle; 60° is the universal angle, 20° suits high-gloss surfaces and 85° suits matte surfaces; curved and…
Before buying a coating thickness gauge, confirm one by one: substrate and principle, range and accuracy expression, instrument type, calibration-certificate form and traceability body, standards-conformance documents, unit switching, data capability,…
The completeness of a thickness-measurement system relies on four classes of accessories: the probe (replaceable and wear part), the reference shim (runs per-shift verification), the couplant (the medium for ultrasonic…
