ZX-SZ Transformer Oil Acid Tester: Automated Precision for Oil Condition Monitor

For maintenance engineers and laboratory technicians responsible for the health of critical electrical assets, monitoring the acid value (neutralization number) of transformer and turbine oils is a fundamental diagnostic task. The traditional manual titration method, while effective, is time-consuming, reagent-intensive, and susceptible to operator variability. The ZX-SZ Transformer Oil Acid Tester represents a significant technological step forward, offering a fully automated, precise, and user-friendly solution for this essential analysis.

The Critical Role of Acid Value Testing

Acid value measures the concentration of acidic constituents formed in insulating oil due to oxidation and degradation. A rising acid number is a clear indicator of deteriorating oil quality, which can lead to corrosion, sludge formation, and ultimately, compromised dielectric strength and impaired cooling. Regular, accurate testing is therefore paramount for predictive maintenance, enabling timely oil reclamation or replacement before costly equipment failure occurs.

How the ZX-SZ Tester Revolutionizes the Workflow

The ZX-SZ transformer oil acid tester integrates modern computer control and robotics to transform the testing process. Its core design philosophy is "load and proceed." The operator simply prepares the oil sample in a beaker, places it in the designated station, and initiates the test via the intuitive touchscreen interface. The system then executes a pre-programmed sequence autonomously:

1.Automatic Cup Seeking & Identification: The instrument locates and recognizes the sample beaker.

2.Precision Dispensing & Stirring: A unique liquid pump system accurately dispenses the required solvent and titrant. Integrated stirring ensures perfect homogenization.

3.Potentiometric Titration: The system performs a automated titration, using an electrode to detect the precise endpoint (neutralization point) potentiometrically, eliminating subjective color-judgment errors.

4.Intelligent Calculation & Data Handling: An onboard microprocessor calculates the acid value in mg KOH/g based on the titrant consumption. Results are displayed, stored internally, and can be sent to the integrated printer for a permanent record.

Key Technical Features for the Demanding Technician

Beyond automation, the ZX-SZ is engineered for technical excellence and reliability, as evidenced by its specifications:

1.High Accuracy Across a Broad Range: The instrument covers a wide linearity range from 0.001 to 0.900 mgKOH/g. Critically, it maintains high precision even at very low levels (±0.003 mgKOH/g error below 0.100 mgKOH/g), which is crucial for monitoring new or freshly regenerated oil.

2.Superior Measurement Fidelity: A correlation coefficient (R²) of 0.999-0.9998 confirms excellent linearity of the calibration. A recovery rate of 99-102% demonstrates high accuracy against known standards.

3.Excellent Repeatability: With a Relative Standard Deviation (RSD) of 2-5%, the instrument ensures consistent results run-after-run, a key factor for reliable trend analysis.

4.Built-In Diagnostics: The self-checking function is a vital feature for technicians, allowing for quick verification of the instrument's health, including pump function and sensor status, ensuring data integrity.

5.Enhanced Usability: The 5.4-inch large color LCD touchscreen provides a clear, interactive man-machine interface for easy operation, method setup, and data review.

Conclusion: A Tool for Enhanced Asset Management

For the technical professional, the ZX-SZ Transformer Oil Acid Tester is more than just a lab instrument; it is a productivity and reliability tool. It dramatically reduces hands-on time, minimizes human error, and standardizes the testing procedure. By delivering fast, accurate, and auditable results, it empowers maintenance teams to make confident, data-driven decisions about oil condition, directly contributing to extended equipment life, reduced downtime, and optimized maintenance budgets. Its robust design and automated workflow make it an ideal choice for utility labs, industrial facilities, and service companies dedicated to superior asset care.
