The new byko-test MPOR from BYK-Gardner is specially designed for measuring very thin coatings. Its dual sensor with magnetic-inductive Fe and NFe probe automatically recognizes the substrate. Premagnetized substrates, which are used in the automotive and other industries, do not influence the readings. The readings are displayed on two illuminated LCD displays -- one large display on the front panel and another on the top. An integrated radio transmitter transfers the readings wirelessly to the computer with an optional radio receiver. The byko-test MPOR displays the status and indicates if the measured value is within specification.
