PPM – Parts Per Million

Parts Per Million (PPM) is a ratio used to describe the maximum measurement error or resolution of pressure measurement equipment.

PPM is most often used as an alternative way of expressing very small percentage values for high accuracy measurement standards such as dead weight testers and high resolution digital displays.
