1. Things to Consider When Buying Ultrasonic Calibration Block in China

When you want to buy an ultrasonic calibration block, you must consider many parameters. These include:

Accuracy refers to the variation between the expected result and the obtained result of a test. Precision refers to the closeness of repeated measurements of a constant quantity.
