The proliferation of non-linear loads such as variable frequency drives, rectifiers, induction furnaces, and LED lighting systems is making harmonic pollution a major headache for industrial plants.

An overview of electrical porosity testing for finding pinholes and holidays in cured non-conductive protective coatings, including low- and high-voltage detector selection.

A practical guide to Barcol hardness testing for rigid plastics and soft metals, from selecting a test location to verifying readings.

A practical guide to maintaining a coating thickness gage through planned calibration checks, careful probe handling, cleaning, and proper storage.

A practical overview of inspection points for polyurea coatings on steel, concrete, and other substrates, including surface profile, climate, thickness, and adhesion.

Using a coating thickness gauge helps identify wear on an OPC printer drum rather than relying solely on visual inspection of the surface. The service life of an OPC drum is often considered to have significantly declined when the coating has worn by approximately 5 to 15 μm. When the wear approaches half of the original coating thickness, the drum may be removed from service depending on the remanufacturer’s quality control procedures.

A practical guide to selecting a conformal coating thickness measurement approach for printed circuit boards based on substrate construction, available access, and coating requirements.

Erosion and corrosion can gradually reduce the material thickness of pipelines, storage tanks, boilers, pressure equipment, and various other industrial structures. Ultrasonic thickness gauges also provide the basis for identifying areas of wall thinning, planning inspections, and supporting maintenance decisions.

A practical overview of measuring blanket, packing, and plate thickness on offset presses, including non-destructive measurement considerations and probe selection.
