A fully automatic testing device that utilizes a three-cup extraction approach to accurately detect the acid value of insulation oil.

Key Advantages It boosts work efficiency and testing accuracy while reducing operators’ exposure to samples and reagents for maximum personal safety. The instrument comes with solid reagents; just follow the manual to mix on-site with ordinary chemicals available at local stores—easy to operate, cost-effective, and free from the hassle of shipping dangerous chemicals over long distances. It realizes full automation: from sample scanning, extract feeding, blank titration and measurement, to waste draining, auto-cleaning, shutdown, and result output (display & print). With the capacity to test 1–6 samples per startup, it ensures high working efficiency.

Troubleshooting
1. The peristaltic pump tubing is prone to wear and tear. Before use, please carefully check the tubing for damage or adhesion to prevent the instrument from malfunctioning. If any abnormalities are found, it is recommended to replace the tubing. After using the instrument, please release the pressure arm of the peristaltic pump to prevent the tubing from being damaged by prolonged compression.
2. If the instrument has not been used for more than three months, it is recommended to recalibrate it with a standard acid solution.
3. The container used to prepare the extraction solution must be dry and free of moisture, and stored in a sealed container.
4. When performing continuous tests, the sample cup does not need to be cleaned. However, if there is a time interval between tests, the sample cup must be cleaned and completely dried before use.
5. After completing the test, you must perform the "clean and shut down" procedure.
