Máy đo độ dày sơn, lớp phủ để bàn -Thickness Measuring Instrument NeurTek Instruments

The Measuring Principle

The Thickness Measuring Instrument NeurTek Instruments 548 functions in accordance with the same measuring principle of the standardized wedge cut method as the Thickness Measuring Instrument NeurTek Instruments.

The Measuring Instrument

The Thickness Measuring Instrument NeurTek Instruments 548 has been developed to extend the range of the application of the Thickness Measuring Instrument NeurTek Instruments, especially targeting sensitive drillings, particularly into rigid/brittle materials. It is possible that, already at minor eccentric irregular running of the drill used or of its centre axle, such materials can be subject to breaking off of the cutting edges including chipping off, leading afterwards during the optical measurement with the microscope also to limitedly definable transitions between the layers to be measured.

To minimise these limitations the Thickness Measuring Instrument NeurTek Instruments 548, a convenient tabletop unit, is equipped with an improved rotating/sliding high precision axle-bearing device. Although the application can be considered as mobile in the range of the length of the mains cable, it is nevertheless the question of a laboratory equipment. It can either be held in hand or used in connection with the measuring stand that is included in the scope of supply.

The appropriate measuring microscope is not integrated in the housing, as for the Thickness Measuring Instrument NeurTek Instruments, but is available separately, if required, as a self-contained component (e. g. for the evaluation of damages of lacquers, corrosion creep, pores etc.) which results in the slender handy design of the Thickness Measuring Instrument NeurTek Instruments 548.

The Operation

In principle, the Thickness Measuring Instrument NeurTek Instruments 548 is used in the same way as the Thickness Measuring Instrument NeurTek Instruments:

•Application of a contrast mark.

•Placing the instrument onto the specimen, positioning the drill directly above the test point. When using the stand, position the test point on the specimen directly beneath the drill. Then fix the specimen from underneath by rotating the pressure plate.

•Drilling through the layer to the substrate.

•Carrying out the measurement with the help of

the microscope considering the scale factor.

The geometry of the specimen admissible for the coating thickness measurement with the Thickness Measuring Instrument NeurTek Instruments 548 depends on whether the drilling unit is used with or without drilling stand.
