型號 : Trek 370

The 370 employs an electrostatic field-nulling technique which achieves high DC stability and high measurement accuracy even if the probe to measured surface spacing changes. This permits measurements of either stationary or moving surfaces without the need to establish fixed spacing to maintain accuracy.

An automatic gain feature of the Model 370 eliminates the need for manual adjustment when changing probes or when changing the probe to measured surface separation.
