Checkline Coating Thickness Gauges

Q: What is the difference between magnetic and eddy current measurement principles?

Magnetic principles are used for non-magnetic coatings on ferrous substrates (steel and iron) by measuring changes in magnetic flux. Eddy current principles are used for non-conductive coatings on non-ferrous metal substrates (such as aluminum) by measuring electrical impedance variations.

Q: Do electronic gauges require frequent manual calibration adjustments?

Most modern electronic gauges (like the PosiTector 6000 ) arrive factory-calibrated and ready to measure. Performing a quick zero check on an uncoated piece of the actual job substrate ensures maximum measurement precision before starting an inspection.

Coating Thickness Gages, also known as Dry Mil Gauges or Paint Thickness Gauges are precision measure instruments that use magnetic and eddy current principles to measure coating thickness on both ferrous and non-ferrous metals. Coating thickness gages measure the thickness of paint plating, coatings and galvanizing on iron steel.

When should I choose a mechanical banana gauge over an electronic gauge?

Mechanical magnetic pull-off gauges (such as the MikroTest F6) operate entirely without batteries or electronics, making them ideal for hazardous, explosive, or spark-sensitive environments where electronic devices are prohibited.
