The benzene crystallization point meter is mainly used to determine the crystallization point of benzene. Its working principle is: the sample is cooled in a cold bath at 0°C, and after solid precipitation occurs, the highest temperature point at which the sample temperature rises is measured. The benzene crystallization point instrument usually consists of a temperature measuring device, a cold bath (refrigeration tank), a large test tube, a small test tube and a testing system.
