Dual-Probe Precision for Auto & Metal Surfaces-The -300PRO Paint Thickness Gauge uses magnetic induction + eddy current probes to auto-detect metal substrates (FE/NFE), delivering lab-grade accuracy (±3% +1μm) for automotive paint, chrome, and enamel coatings. Perfect for collision repair shops and detailers! 1μm Ultra-Accurate Resolution & Multi-Calibration-Measure coatings from 0-2000μm with unmatched 1μm precision. Switch between μm, mm, or mils instantly, and use zero/multi-point calibration to reliability on curved or uneven surfaces. Ideal for professional auto body inspections! Smart Backlit LCD with Data Tracking-The high-contrast LCD displays clear readings in sunlight or dark garages. Track avg/max/min/DIF for non-destructive testing, prep, and quality control-no more manual calculations! Beyond Cars: Industrial-Grade Versatility-From factory metal plating checks to chemical industry QC, the -300PRO thrives in labs, workshops, or harsh environments. Weather- design ensures stable performance from -10°C to 50°C. For optimal accuracy, perform a zero-point calibration before testing. Quick Vertical Probe Placement: Firmly the probe vertically onto the . A beep confirm the measurement is complete.Lift for Next Measurement: Raise the probe at least 2 cm away from the to reset for subsequent tests.Auto-Shutdown Feature: The device powers off automatically after 60 seconds of inactivity if enabled.
