Macroscopic entanglement represents itself in nonlocal correlation of the entropy productions of classically insulated dissipative processes. Nonlocal correlation detector is a device including some, well protected from any local impacts, spontaneous dissipative probe-process, the entropy variation in which is related with a measurable variable (signal). Experimentally convenient example of the source-process is a phase transition. The experiment on measuring of response of electrode macroscopic correlation detector to the process of liquid nitrogen evaporation has been carried out. The signal extremum is reached much later than the end of evaporation. The detector response begins at once as the evaporation beginning, while classical local temperature impact has retardation equal to 1.5 hours. The form of response is essentially asymmetric, with long relaxation time.
