The byko-test MPOR is specially designed for measuring very thin coatings. Its dual sensor with magnetic-inductive Fe and NFe probe automatically recognizes the substrate. Also, premagnetized substrates, which among others are used in the automotive industry, do not influence the readings. The readings are displayed on two illuminated LCD displays: one large one on the front panel and another on the top. Data can be easily read even on measured parts, which are difficult to reach. An integrated radio transmitter transfers the readings wirelessly to the computer with an optional radio receiver. Furthermore, the test displays the status and indicates if the measured value is within specification. The memory has space for 999 measured values. Additionally, statistic functions facilitate the processing of the measured data.
