An Miao AC-990 Coating Thickness Gauge is a battery-powered portable measuring instrument , which uses the principle of magnetic induction and eddy current. The measurement method complies with international standards ISO2178, ISO2360 and national standards GB4956, GB4957. It adopts computer technology non-destructive testing technology and other professional technologies to accurately measure the thickness of the measured object without damaging it.
* The F-type probe can directly measure the thickness of the non-magnetic coating layer (such as: paint magnetic-conductive materials (such as iron and nickel). It can be applied to the thickness measurement of electroplating layer, paint layer, enamel layer, aluminum tile, copper tile , babbitt tile, phosphating layer, paper, and also can be used for thickness measurement of hull paint and attachments of underwater structural parts.
* NF type probe can measure the thickness of the insulating , such as paint, plastic, rubber coating on the surface of aluminum, copper, zinc, non-magnetic stainless steel and other materials , and can also measure aluminum or aluminum The thickness of the anodic oxide layer of the alloy material .
* The spring guide sleeve probe with wear-resistant hard metal probe can not only measure on hard or rough surfaces, but also ensure that the probe has constant pressing force and stable sampling value.
* Wide measuring range and high resolution.
* Automatic memory calibration value, easy to use.
* Integrated structure, small size and light weight.
* Digital backlight display, no parallax.
* With the optional RS232C software and cable, it can communicate with PC computer to realize the functions of data collection, processing, analysis and printing.
* The AC-990 Coating Thickness Gauge is equipped with an automatic shutdown function to save power.
