🔬 Measurement Methods

Magnetic Induction (F-probe): ferrous substrates only
Eddy Current (N-probe): non-ferrous metals
Ultrasonic: non-metal substrates, multi-layer
Dual-mode (FN): auto-detects ferrous/non-ferrous

📏 Typical Ranges

Paint on steel: 25–2000 µm
Galvanizing: 5–500 µm
Anodizing: 1–100 µm
Thermal spray: 50–5000 µm
Plastic on metal: 10–3000 µm

⚠️ Limitations

Substrate must be ≥0.5 mm thick for accurate reading
Curved surfaces <25 mm radius require special probes
Magnetic substrates affect eddy current readings
Calibrate with certified foils before measurement
