Pressure testing equipment calibration is important in ensuring that you collect accurate and reliable data through your work. While different devices and systems will require different calibration techniques, all calibration depends on either a primary or secondary (otherwise known as “transfer”) standard. But what, exactly, is the difference between primary vs secondary standards?
