Ultrasonic Thickness Gauge GM100

Ultrasonic Thickness Gauge GM100 (Digital Metal Thickness Tester)

The GM100 ultrasonic thickness gauge is a high-precision digital instrument designed for non-destructive thickness measurement (NDT) of industrial materials. Using ultrasonic wave technology, it accurately measures the thickness of metals, plastics, ceramics, and other solid materials without causing any damage.

This handheld device is widely used for inspection, maintenance, and quality control in industrial environments where material integrity and safety are critical.

Specifications

• Display mode: four-digit LCD display
