Pacific Sensor HFRR test specimens meet all ASTM D6079 requirements. Their specimens are equivalent to those from PCS Instruments as determined in two ASTM Interlaboratory Studies. They offer single-sided and double-sided test specimens. Their unique double-sided specimens can be used to run two tests and are the best value in the industry, reducing the cost of testing by 25 percent. They are the only US-based manufacturer of HFRR test specimens and the only manufacturer to prove equivalency to PCS through an ASTM Interlaboratory Study. Pacific Sensor is ISO 9001:2015 certified and ISO/IEC 17025:2017 accredited. They supply HFRR specimens to most of the ISO 17025 certified fuel testing laboratories in North America. Their team includes experienced engineers and PhD scientists that have extensive experience in fuel and lubricant testing. Since they are laboratory experts, they understand that repeatability and responsiveness matter. 100% of specimens are inspected to verify conformance to ASTM D6079 and every order of HFRR specimens is shipped with a certificate of conformity to ASTM D6079.

They offer single-sided test specimens in packs of 25, 50 and 100, as well as 100 double-sided discs which yields 200 tests.
