The Fluke ST-55 Operating Fluid is a type of mineral oil that is used as a pressure medium for some Fluke Calibration products, such as the E-DWT Electronic Deadweight Tester (6531, 6532), Hydraulic Comparison Test Pumps (P5514, P5515), and the P31XX Series Pneumatic Deadweight Testers.
It has a low viscosity and a high flash point, which makes it suitable for high-accuracy pressure calibration. It is sold in 1-quart bottles.
