The probe of DT-156 coating thickness gauge can work under the principle of electromagnetic induction and eddy current. Under the automatic mode (AUTO), the two principles can be automatically transformed by visual measurement of matrix, or can be automatically and non-automatically transformed by menu.Features: This coating thickness gauge can be used in the field of non-destructive, fast and high precision coating thickness gauges. The measurable coating layer includes the thickness of the non-magnetic coating layer on the surface of the magnetic material and the thickness of the insulating coating layer on the non-magnetic metal surface. Low power and error prompts, can be set to automatically shut down, easy to use. Support continuous and single measurement mode, direct working mode and group working mode. The average, maximum, minimum, standard deviation, and statistics can be counted and displayed. With a ruby probe for one or two point calibration. Support USB connection and transfer data to the computer, save 400 measurement data, and delete measurement data and group data in real time. It is an ideal auxiliary manufacturing tool for paint, anti-corrosion, electroplating, automotive industry, ship transportation, aircraft manufacturing and so on. It can work stably in the laboratory, on-site and outdoors, for vehicle overhaul and evaluation, aviation aircraft manufacturing, shipbuilding, mechanical equipment quality assessment, hardware processing and manufacturing, etc. Specification: Condition: 100% Brand New Material: ABS Sensor probe Fe NFe Working principle Magnetic induction Eddy current Measurement range 0-1250um
