UM-2 Series Ultrasonic Thickness Gauge

Measuring Range:0.8-300 mm
Through Paint Mode:3-20 mm (only UM-2D)
Resolution: 0.01 mm
Application: UM-2 series ultrasonic thickness gauges are used for measuring Metal and Nonmetal materials i.e. Plastic, Steel, PVC, Glass Plates and Pipes. They can be widely used in the fields such as manufacturing and metal processing, etc. It can also make detection on various kinds of pipes and pressure vessels of the manufacturing facilities about their thickness lossing after corrosion.

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.
