摘要: The present invention provides a pressure-medium oil comprising at least one of a hydrocarbon compound and an ether compound and having the following properties (1) to (4): (1) a kinematic viscosity as measured at 40° C. of 2 to 30 mm2/s; (2) a viscosity index of 110 or higher; (3) a density as measured at 15° C. of 0.86 g/cm3 or less; and (4) a pour point of −50° C. or lower. The pressure-medium oil does not solidify under an ultra-high pressure, for example, 1.5 GPa or higher, and has a low pour point and excellent compatibility with test samples and with the material of the apparatus employed in the test.
