Fully Automatic Water-Soluble Acid Tester: Setting New Standards in Oil Testing with ISO Compliance; Goldhome Specializes in Insulating Oil Analysis and Testing
In the power and petrochemical industries, the content of water-soluble acids in insulating oil and lubricating oil is a key indicator for assessing the corrosiveness and degree of aging of these oils. Water-soluble acids primarily consist of low-molecular-weight organic acids and inorganic acids, which are highly corrosive to metals and are the direct cause of corrosion in solid insulating materials of power equipment such as transformers. Against this backdrop, Goldhome's fully automatic water-soluble acid tester (Colorimetric Method) strictly adheres to relevant ISO standards and the Chinese national standard GB/T 7598-2008. With its exceptional automation capabilities and measurement accuracy, it has become the ideal choice for both batch testing in laboratories and rapid on-site screening.
Five Core Features of the Fully Automatic Water-Soluble Acid Tester
1. Fully automated process, significantly improving testing efficiency: Controlled by a microprocessor, the tester requires users to simply inject oil samples and distilled water in the standard ratio. The instrument then automatically performs a series of operations, including heating, temperature control, reciprocating agitation, oil-water separation, color development, colorimetry, data calculation, cleaning, and printing. It can process 1 to 6 samples per batch, with a testing cycle for a single sample reduced to just a few minutes. Compared to traditional manual titration methods (which take 15 to 30 minutes), efficiency is improved by 5 to 10 times. The fully automated process design effectively reduces direct contact between laboratory personnel and chemicals, enhancing operational safety.
2. High-precision colorimetric measurement and dual-indicator system ensure accurate results: The product's core detection principle employs colorimetry, performing precise measurements based on the differences in how substances absorb light at specific wavelengths. Key models utilize high-precision color sensor chips to directly analyze the color of the sample. Goldhome's HMJS-3 model is specifically equipped with a dual-indicator system using bromophenol green and bromophenol violet, ensuring precise pH determination across both acidic and alkaline ranges. The measurement range covers pH 3.8 to 7.0, with a measurement error of ≤±0.05 pH and repeatability of ≤0.05 pH. This detection accuracy far surpasses that of traditional manual titration methods and is not affected by the color of the oil sample.
3. Robust multi-position batch processing capability efficiently supports high-throughput testing: The product line offers flexible configurations ranging from 1 to 12 sample positions. Goldhome's HM203 model can measure 3 samples at once, making it suitable for routine laboratory testing. The HMJS-3 model, on the other hand, features 12 sample positions (supporting 6 sets of parallel testing) and is specifically designed for high-throughput batch testing in laboratories. It supports the simultaneous processing of multiple sample sets, significantly increasing testing throughput per unit of time and greatly reducing the workload on staff.
4. Comprehensive safety features and intelligent self-diagnostic system to reduce operational costs: In terms of safety, the system employs a fully enclosed, sealed design that effectively isolates the interior from the atmosphere, preventing reagent evaporation and minimizing interference from atmospheric carbon dioxide on test results. This also reduces fire risks for operators, while automated waste liquid management minimizes manual exposure to organic solvents, ensuring compliance with ISO 14001 environmental standards. The equipment also features built-in fault self-diagnosis capabilities, guiding users through voice prompts and on-screen alerts to resolve common issues such as burette blockages and reagent shortages. Annual maintenance costs account for 8% to 12% of the equipment's price, lower than the 15% to 20% typical of traditional equipment, with maintenance efficiency improved by approximately 30%.
5. Comprehensive data management and traceability to support digital oil monitoring: The equipment typically features a large LCD touchscreen and a thermal printer, supporting real-time data display and automatic printing. High-end models support data export to USB drives, cloud synchronization, and integration with LIMS systems, with built-in storage for hundreds of data sets to meet traceability requirements of quality management systems such as ISO 17025. Some models also support RS232 or USB communication with computers, facilitating long-term data archiving and remote management.
As a company certified under both the ISO 9001 Quality Management System and the ISO 14001 Environmental Management System, Goldhome's products are exported to more than 30 countries and regions, including Europe, the Americas, Africa, the Middle East, and Southeast Asia. Looking ahead, Goldhome will continue to focus on the fields of high-voltage electrical testing and oil and chemical analysis. We will integrate cutting-edge technologies-such as deep learning models for predicting oil degradation trends, IoT integration, and remote data sharing-into our product development. We are committed to providing the global power systems and petrochemical industries with testing solutions that offer higher precision and greater automation, and to building an intelligent big data platform for oil quality monitoring.
