FAQs

1. Can the Multifunctional Low Temperature Tester be used for simultaneous testing of multiple samples?

Multifunctional Low Temperature Tester is equipped with four independent cold troughs, each having dual test baths, which allows multiple samples to be tested at the same time. This design is suitable for high-throughput laboratories that need to run different low-temperature tests across various fuel or oil types. Operators can assign different procedures to each trough as needed. The device includes an interface that makes it easy to monitor and control all test chambers.

2. How does the Multifunctional Low Temperature Tester handle samples with unusual flow characteristics or high wax content?

The Multifunctional Low Temperature Tester can test high-viscosity or wax-rich samples by allowing users to adjust cooling rates and set testing conditions precisely. The instrument’s wide temperature range down to –70?°C and stable thermal performance make it ideal for heavy oils, crude oils, and specialty fuels. However, users must ensure that samples are homogeneous and free of particles to avoid inconsistent results or test interruptions. It maintains accurate performance even when wax starts to form early in the cooling process.

3. What should a user check before starting a test on the Multifunctional Low Temperature Tester ?

Multifunctional Low Temperature Tester should be placed on a stable surface with proper ventilation before use. Users must check that the selected cold trough has reached the desired temperature and that the sample is clean, well-mixed, and free of water or debris. It is important to use dry glassware and position it correctly to ensure valid results. The tester’s control screen should be reviewed to confirm that the correct test parameters are selected.

4. What are common user mistakes to avoid during cold filter plugging point testing on the Multifunctional Low Temperature Tester ?

One common mistake with the Multifunctional Low Temperature Tester is using unfiltered or poorly prepared samples, which may cause the filter setup to clog and produce invalid results. Another issue is not checking that the vacuum pressure and filter system are sealed properly, which can affect test accuracy. Users should also make sure the cold bath has fully stabilized before starting the test. Incorrect timing or misinterpreting when the flow stops can lead to unreliable values.

5. What should users do if the Multifunctional Low Temperature Tester does not cool properly or takes too long to reach the set temperature?

The Multifunctional Low Temperature Tester should be operated in a room with a temperature below or equal to 30?°C to ensure proper cooling. Users should check that the unit's ventilation areas are clear and clean to allow efficient airflow. It is also important to confirm that the power supply is stable and the cooling cycle has been running for an adequate amount of time. If the problem continues, users should refer to the maintenance manual or contact our support team for further assistance with the refrigeration system.
