As a basic miscibility testing method, the observation method is widely used in industrial preliminary screening and laboratory rapid verification scenarios, thanks to its convenient operation, low cost, and flexible applicability. However, traditional visual observation has inherent limitations such as strong subjectivity, suitability only for qualitative judgment, and inability to accurately quantify miscibility, making it hard to meet the high-precision requirements under complex working conditions.

To overcome the limitations of traditional measurement methods, XIATECH has successfully developed a more versatile miscibility tester through technological innovation. Equipped with a high-precision imaging system and self-developed image recognition & analysis software, thedevice can real-time detect sample phase changes and accurately identify the mutual solubility temperature of two phases, completely eliminating the subjective deviation of traditional visual observation and significantly improving the reliability of test results. Its specialized structural design effectively expands temperature and pressure testing boundaries: the low-temperature limit can reach -30℃ (lower temperatures customizable), the high-temperature limit up to 100℃, and it has a pressure-bearing capacity of 5 MPa, meeting miscibility testing needs for high-temperature and high-pressure systems in most scenarios. Additionally, a built-in safety pressure relief mechanism automatically relieves pressure when system pressure exceeds the set value, effectively avoiding the risk of damage to test containers under high pressure and ensuring safety and reliability during testing.

Based on the above technical features, the device can be applied to the following core scenarios:

1) High-temperature and high-pressure miscibility testing：Suitable for accurate miscibility measurement of fluids within -30~100℃ and 0~5 MPa (temperature and pressure customizable).

2) Determination of two-phase separation curves: Precisely measures two-phase separation temperatures under different ratios to plot separation curves.

3) Critical temperature testing: Determines critical temperature via a high-precision real-time temperature monitoring system.

4) Critical pressure testing: Accurately measures critical pressure relying on a high-precision real-time pressure monitoring module.
