What are calibrators and how do they work?

Calibrators are devices used to verify the accuracy and performance of measuring instruments such as sensors and meters. They work by providing a known and controlled reference signal to the measuring instrument being tested, allowing the instrument to display a reading. The calibrator then compares the instrument’s reading to the known reference signal to determine the accuracy of the instrument. Calibrators are used in various industries including process control, laboratory analysis, and quality control. There are different types of calibrators, including acoustic calibrators, vibration calibrators, and flow calibrators, each designed to calibrate specific types of measuring instruments.
