Ranges

A specific range and resolution will require a particular probe size/model. Range/Resolution may also be affected by the target material.

Probes are identified by their diameter in mm.
A U5 probe has a 5mm diameter.Larger ranges require larger probes.

Custom ranges are always available.

Listed specifications are for standard target materials.
