The PCS HFRR is the industry leading instrument for analysing diesel fuel lubricity. PCS are the original manufacturers of the HFRR instrument and are the only instrument supplier specified on the following test methods: ISO 12156, ASTM D6079, ASTM D7688. With over 30 years of development experience and continual design, quality, and user experience improvements, we remain at the forefront of the market. This next-generation HFRR comes with a host of refinements, including active environmental control replacing less accurate passive methods and removing the need to use salt solutions for humidity control. This allows for quicker attainment of ambient humidity and temperature targets to even tighter tolerances.
