Refrigerant/Oil Miscibility Tester
Developed based on SH/T 0699-2023 standard, it enables high-precision measurement of two-phase separation temperature for refrigerant and lubricating oil mixtures with different proportions.
The MI7100 Miscibility Tester developed by XIATECH complies with the SH/T 0699-2023 standard. It adopts the observation method as its testing principle to obtain the miscibility temperature of mixed working fluids of various refrigerants and oils. The device features a wide temperature measurement range (-30~100℃), which can meet both high-temperature and low-temperature miscibility measurement requirements. 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 groups of 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.
