With different external probes, the gauge can be applied to measuring thickness of non-magnetic coating on magnetic metal substrate, as well as non-conductive coating on non-magnetic metal substrate.
Five types of probes (F400, F1, F10, N1, CN02) are available for different application. F10 probe measures up to 10mm.
Two measuring modes: single or continuous, changeable.
Two calibration methods can be applied to the gauge; And the system error of the probe can be corrected with the basic probe calibration method.
Measured values and user information are shown on a large, easy-to-read LCD. A display back light ensures easy reading of screen data in poorly-lit conditions.
