PosiTest Magnetic Coating Thickness Gauge

Quickly check if minimum coating thickness is complied with
The rotating analog display can be set to the minimum required coating thickness. When this mimimum value is set, the gauge is ready for quick minimum coating thickness verfication and the gauge can be placed on the material.

When the button on top of the gauge is pressed and the probe clicks and stays down, magnetically attached to the material, the thickness of the material is smaller than the required minimum thickness. If the probe does not stay clicked down on the material, the thickness is greater than the required minimum thickness. Using this measuring method the operator can quickly verify large surfaces.

Quickly check if maximum coating thickness is complied with
The required maximum coating thickness can be verfied just like the minimum required coating thickness gauge above. Set the rotating analog display to the maximum required coating thickness. Place the gauge on the material to be verified and press the button on top of the gauge. When probe clicks to the material and stays down or magnetically attached to the surface, the coating thickness is smaller than the set maximum value. When the probe does not magnetically attach and comes up again, the coating thickness is greater than the set maximum value.

Determine the actual coating thickness
When the operator would like to know the actualy coating thickness on the substrate this can be rotating the analog display to the maximum available coating thickness value. Place the gauge on the material and press the button on top of the gauge. The probe clicks and is magnetically attached to the material. Next, turn the analog display toward the minimum value until the probe detaches from the material and jumps upward again. The value displayed on the display is the actual coating thickness.
