Probes, Ranges, and Resolutions (Probe Dependent)

Larger Probe Diameter = Larger Range
Target: Flat, Diameter > 3 X Probe Diameter
or custom calibration required

Probes can be ordered as vacuum compatible; custom probes are available.

Standard and Fine Ranges, Resolutions, Thermal Drift

Listed specifications are for standard target materials: Nonferrous Al 6160, Ferrous 4140 Steel.
"Fine" Range calibrations are approximately one half of the standard range and provide higher resolutions.
