High voltage phase balance tester

1. Product Introduction

Developed based on the cycle analysis methodVLE1000High voltage phase balance testerBy using a liquid-phase circulation pump to force two-phase flow to achieve system equilibrium, it is possible to measure the phase equilibrium parameters of high-pressure systems within the range of 01-4 MPa; Sampling and analysis of gas-liquid two-phase samples can be achieved by connecting chromatography instruments, which have the advantages of high temperature measurement accuracy, wide pressure measurement range, and accurate measurement; By combining self-developed programs, automatic temperature control, automatic pressurization, automatic sampling, and data analysis can be achieved. It can be used to test the gas-liquid phase equilibrium of various pure and binary/ternary systems, and is suitable for measuring the phase equilibrium of low boiling point refrigerants and their mixtures.
