The UM-2 series thickness gauge has extremely high measurement performance, and the displayed value has high stability and accuracy.
We launched the through coating technology in 2006, which is used on UM-2D. It can measure the thickness of the substrate directly without removing the surface coating of the test object. The applicable coatings for this function are: paint layer, plastic coating, etc. This function is achieved by measuring two continuous bottom echoes of the substrate, it also has many advantages: no zero point calibration, high stability of the indication, and zero drift.
