Introduction of High Precision Acid Value Tester (Automatic Color Indicator Method)
This automatic acid value tester is designed and implemented in accordance with GB/T 264. It adopts the color indicator method and is a fully automatic measuring instrument capable of accurately detecting the acid value of insulating oil, transformer oil, and other petroleum products. Acid value is a critical parameter for assessing oil oxidation and degradation.
Advantages of the Automatic Acid Value Color Indicator Tester
User‑friendly interface
The instrument features a 7‑inch LCD screen with a compact and elegant design, making operation straightforward and intuitive.
Reliable control and detection
A single‑chip microcontroller system manages the entire process. The detection module incorporates imported laser equipment, which offers low power consumption and a long service life.
Fully automated testing process
After loading the sample and pressing the start button, the tester automatically performs the following steps: reagent extraction, neutralization, cup rotation, and detection. Once the test is completed, the instrument automatically stops and prints the results, minimizing manual intervention and improving repeatability.
Application Scenarios & Added Value
Typical users
Electric power utilities, transformer maintenance laboratories, oil refineries, petrochemical plants, and quality inspection centers that need to monitor the acid value of insulating oils, lubricating oils, and other petroleum products to prevent equipment corrosion and ensure safe operation.
Quality assurance
Each unit undergoes factory calibration and performance verification. Our ISO9001:2000‑certified quality management system ensures consistent reliability from design through production. The instrument’s high repeatability (0.002 mgKOH/g) guarantees dependable results.
Operational benefits
The 6‑cup design allows batch testing, improving laboratory efficiency. The automatic printing and data recording functions support paperless documentation and traceability.
