Product Description
Brief introduction
This device is a portable meter. It is capable of measuring coating thickness quickly, precisely and without injury, both for the laboratory and engineering environment. It is currently widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and testing fields, and is essential for material protection major.
This device meets the following criteria:
GB/T 4956-1985 non-magnetic coating thickness measurement on magnetic metal substrate, Magnetic Method
GB/T 4957-1985 non-conductive coating thickness measurement on non-magnetic metal substrate, Eddy Current Method
JB/T 8393-1996 Magnetic & Eddy Current coating thickness measurement
Features
1.Thickness measurement using both Magnetic Method to measure the non-magnetic coating on a magnetic metal substrate and Eddy Current Method to measure the non-conductive coating on a non-magnetic metal substrate.
2.Single-point or two-point method could be used to correct probe system deviation, in order to ensure the accuracy of the device in the process of measuring.
3.Automatic identify ferrous and non-ferrous substrate quickly.
4.Power voltage indicator.
5.Speaker beep while operating.
6.Power-off automatically when idle; manually power-off available.
7.Negative display function to ensure the accuracy of zero point calibration.
8.Showing average, max, min value.
