The SGVS-1 Transformer Oil Moisture Tester was recently officially released. This high-precision micro-moisture analyzer, based on the Karl Fischer coulometric titration principle, is specifically designed for the detection of trace moisture in substances such as transformer oil, insulating oil, petrochemical products, and lithium battery electrolytes.
With the accelerated construction of ultra-high-voltage power grids and the development of new power systems in my country, the trace moisture content in transformer oil directly affects the insulation performance and service life of electrical equipment. Traditional detection methods are slow and lack accuracy, while imported Karl Fischer moisture analyzers suffer from high consumable costs and long maintenance cycles. The launch of the SGVS-1 provides domestic power companies and petrochemical users with a cost-effective domestic alternative.
According to the official user manual, the SGVS-1 uses a 32-bit embedded microcontroller as its main control core, paired with an embedded mini operating system, offering fast analysis speed, simple operation, and a high degree of automation. Its main technical parameters are as follows:
Titration Method: Coulometric Titration (Karl Fischer)
Sensitivity: 0.1μg H₂O
Measurement Range: 3μg～100mg
Electrolysis Current: 0～400mA (Automatic Control)
Accuracy: 10μg～1000μg ±3μg, error no greater than 0.3% for values greater than 1mg
Display: Color LCD touchscreen, full digital keypad operation
Printer: Built-in mini thermal printer (with time recording)
Power Supply: 220V±10%, 50Hz, power <40W
Dimensions: 340mm×295mm×155mm, weight approximately 5.5kg The device supports four calculation formulas and can flexibly switch between units such as mg/L, %, and ppm according to user needs. The intuitive color touchscreen interface supports parameter settings, historical record queries, one-click printing, and data export (RS232 interface). The manual emphasizes its "one-click, automatic testing" feature, significantly lowering the skill threshold for on-site testing personnel.
The company's technical director stated, "The SGVS-1 is designed with ergonomics in mind. Its new design and optimized operating software significantly improve the user experience. We have rigorously controlled the electrolytic cell, electrode system, and stirring control, ensuring stable blank current even in complex environments and guaranteeing excellent repeatability."
The SGVS-1 is widely used in industries such as petroleum, chemical, power, railway, pesticides, pharmaceuticals, and environmental protection. Whether it's detecting trace moisture in transformer oil or analyzing trace moisture in solid, liquid, and even gaseous samples, it provides rapid and reliable results. The manual details electrolyte preparation, electrode maintenance, blank current adjustment, self-calibration, and troubleshooting procedures, providing comprehensive guidance for long-term stable use.
