A powder coating thickness gauge is a specialized instrument used to measure the thickness of powder coating on metal or non-metal surfaces, helping ensure coating quality and durability while minimizing material consumption. Measuring powder coating thickness at the right stage and using the appropriate measurement principle helps maintain coating quality, reduce rework, and optimize the finishing process.

A coating adhesion tester is an essential instrument for evaluating the quality of paints, varnishes, and protective coating systems. The coating must bond sufficiently well to the substrate or underlying coating layer to minimize peeling during use. Depending on the substrate material, coating system structure, test conditions, and evaluation objectives, operators can select from several adhesion test methods, including knife, tape, pull-off, and scratch tests.

A practical overview of ultrasonic coating thickness measurement for wood and wood products, including operating principles, measurement considerations, and process-control benefits.

The PosiTector 6000 FS1 is a non-destructive coating thickness gauge that enables the monitoring of mesh, emulsion, stencil, and dried ink thicknesses in the screen printing process.

The capacitor labels indicated a 10-year lifespan, yet after just two years of service, the casings began to bulge; some even exploded, accompanied by a popping sound and a burnt odor that permeated the electrical room. The maintenance team would install replacements, only for the exact same issue to recur a few months later. This cycle repeated multiple times before anyone finally questioned whether the failures were due to the capacitors reaching the end of their service life or because they were being subjected to conditions beyond their original design specifications.
