Ultrasonic couplant gel improves the ultrasonic signal by displacing air and transferring ultrasonic energy from the transducer to the test specimen. This reduces noise and strengthens the reading from the transducer.

These probes connect to compatible ultrasonic thickness gauges and measure the thickness of pipes, pressure vessels, tanks, ship hulls, and more.

Step calibration blocks check the accuracy of ultrasonic thickness gauges. These blocks vary in size and are marked with thickness measurements. To calibrate gauges, users verify that the gauge reading matches the measurement noted on the block.
