The GM100 Ultrasonic Thickness Gauge is a portable, digital non-destructive testing (NDT) instrument. It works by sending ultrasonic sound waves through a material and calculating its thickness based on how long it takes the sound to return.
The kit in your photo includes:

* Ultrasonic probe (sensor)
* Coupling gel (used between the probe and the test surface)
* Calibration test block
* Carrying case
* User manual
* Batteries
