Portable Handheld Thickness Gauge

Portable thickness gauges utilize ultrasonic or eddy current principles, where a probe emits signals and receives reflected waves from the material. By calculating propagation time or electromagnetic changes, they determine the thickness of coatings and films. These gauges are used for rapid on-site detection of coating thickness on substrates such as metals, plastics, and paper, ensuring that painting and printing processes meet required standards.
Selection
When selecting a portable thickness gauge, consider the material type: use magnetic induction for magnetic substrates and eddy current for non-magnetic substrates, while universal models are compatible with various materials. Match the probe size based on the measurement range, accuracy requirements, and substrate shape. Pay attention to the ease of instrument calibration and environmental adaptability, such as dustproof and waterproof ratings.
