Features: Magnetic induction: You can measure the thickness of the non-magnetic coatings (e.g. paints, plastic, copper, chrome, zinc etc.) on magnetic substrate (e.g. steel, iron and alloys). vertebral effect: you can measure the thickness of the non-conductive coatings (e.g. oxide layer, plastics, varnishes, etc.) on non-magnetic substrate (e.g. copper, aluminium, zinc, tin, etc.). Parameters: Measuring range: 0 to 1300um (0 to 51.2 mils), Units: um, mm and mils, Minimum substrate thickness: F Probe: 0.5mm (0.02"), N Probe: 0.3mm (0.012"); Statistics: Number of measurements, average, minimum, maximum and standard deviation. EASY TO USE: This device applies the design of the standard menu, you can set all by using the instructions and the menu's instructions. There is automatic power off, USB interface for data transfer, low battery and fault indicator. And can also set the high and small value. Many modes: Two modes of measurement: single measurement (Single) and continuous line measurement (Continuous), two groups of measurement: direct (direrct) , three measurement modes: automatic (car), magnetic induction (magnetic) and swivel (Eddy Current). Application: It is professional device for professionals, it can be used to determine the thickness of the paint on the car, it is suitable for offices and specialists, paint shops, chemicals, automotive, shipbuilding, aircraft or light and heavy industry, also for laboratory, workshop and outdoor applications. Description: Measuring principle: Eddy current (F+N). Measuring range: 0~1500um Accuracy: (3%+2um). Resolution: 0.1um Units: um, mils Calibration: Zero calibration and multi-point calibration.
