Abstract: In this paper two organic compounds have been found to replace mercury as transmitting pressure medium according to the function of mercury and its special requirements in the PVT high pressure physical character equipment.We obtain the compressibility coefficient, temperature coefficient and saturated steam of media ZL-Ⅰ and ZL-Ⅱ from experiment, and compare them with mercury. Then, N2 compressibility factor is measured and compared with the standard value, the result of LHSS and PR-EQS. We find it can satisfy the engineering precision requirements.

Key words: transmitting pressure medium, Mercury, Substitute, Experiment
