Comparing the accuracy specifications of pressure calibrators can be a challenging task because different manufacturers specify accuracy in different ways. This means that you can’t simply compare the numbers given in the specification – you need to understand how these numbers are calculated and what they mean in practice.
In this blog post, I look at the different ways pressure calibrator accuracy specifications are presented, explain what they mean, and compare them, as well as take a brief look at what else you should consider when choosing a pressure calibrator.
