Pour point is the lowest temperature at which a fuel or fluid can still flow before solidifying, making it a key indicator of performance in cold climates. If the pour point is too high, fuels and lubricants may gel, causing blockages in engines, pipelines, or filters. Accurate measurement is therefore essential for ensuring usability and safety. Modern instruments, like those from PAC, provide precise, reliable, and repeatable pour point results, helping laboratories and refineries maintain fuel quality and efficiency.
