ElektroPhysik Minitest 650FN Coating Thickness Tester (0 μm – 2000 μm)

Measuring Range: 0 μm – 2000 μm

Measurement Accuracy: ± (2% of the reading + 2 μm/0.08 mils)

Minimum Curvature Radius: 5 mm for convex surfaces, 25 mm for concave surfaces

Minimum Measuring Surface Area: ϕ 20mm

Minimum Substrate Thickness: 0.5 mm for magnetic metals. (This means that to ensure accurate measurement, the substrate must have a certain thickness. If it is too thin, it will not ensure reflectivity, and the measurement result will fall within a certain range.)

Display: 4-digit LCD, 11mm

Measurement Units: User-selectable μm – mils

Dimensions:

Main unit: 70x122x32 mm

Sensor: ϕ 15mm x 62 mm

Weight: 225 grams

Operating Temperature:

Main unit: from 0°C to +50°C

Sensor: from -10°C to +70°C
