Developed based on the SH/T 0699-2023 standard, it can achieve high-precision measurement of the two-phase separation temperature of refrigerant and lubricating oil mixtures with different proportions.

Developed based on the SH/T 0699-2023 standard，it can achieve high-precision measurement of the temperature when the two phases of a mixture separate. Combined with the automatic analysis and measurement software, it can display the temperature and pressure in the system in real-time, making it particularly suitable for measuring the miscibility of various refrigerants and oils.

The device has a wide temperature measurement range (-30~100℃), which can meet both high-temperature and low-temperature miscibility measurements. It also has high pressure resistance (up to 5MPa) and is equipped with an automatic pressure relief function, eliminating concerns about damage to the test container under high temperature and pressure and ensuring the safety and reliability of the testing process. The device is configured with three test chambers, allowing three experiments with different proportions to be carried out simultaneously. In addition, the core device can be taken out at any time, facilitating sample replacement during the temperature control process, which greatly shortens the temperature control time and improves testing efficiency.
