Specifications
SKU: CUSTOM Ultrasonic thickness gauge STG-02
Product overview
It is possible to measure the thickness of various materials, from metals to non-metals.
- The thickness is calculated by measuring the time it takes for the ultrasonic waves output from the transducer to enter the object, reflect off the opposite surface, and return (propagation time).
- It can easily measure the thickness of finished metal processed products, inspect for corrosion on pipes and steel plates, and measure thicknesses in areas that are difficult to measure with calipers or micrometers.
- Equipped with a backlit LCD for convenient use in dark places.
- Equipped with auto power off function to reduce battery consumption.
Features
The probe is placed against the object to measure.

A convenient carrying case is also included.
