Coating Thickness Gauge ZR-220/221/222

Coating Thickness Gauge ZR-220/221/222 main functions: coating thickness ZR-220/221/222 uses two magnetic and eddy current measurement method, non-destructive detection of magnetic non-magnetic metal matrix overlay thickness (e.g., steel alloys and hard magnetic steel on aluminum, chromium, copper, zinc, tin, rubber, paint, etc.) of the instrument, as well as the thickness of non-magnetic metal matrix nonconductive insulating coating layer (such as aluminum, copper, zinc , the rubber on the tin, plastic, paint, oxide film). ● full Chinese menu; ● two measurements; ● work in two ways; ● can store 500 measurements; ● Data Delete function; ● You can set limits; ● measurements outside the boundaries of the automatic alarm; ● supply undervoltage instructions; ● manual and automatic shutdown mode.
