Featured Products
We offer a full range of transformer oil testing equipment. For more product models or other testing needs, please contact us.
Oil BDV Tester
Fully automatic dielectric strength testing with 0-80kV / 0-100kV options. Compliant with IEC 60156, featuring high-precision voltage rise and specific breakdown detection to ensure grid safety.
Gas Chromatograph Analyzer
7/9/11 components. Analysis of dissolved gases (H2, CO, CH4, etc.). Ideal for detecting early internal faults like overheating and arcing in power transformers.
Interfacial Tension Analyzer
Uses the Platinum Ring Method for precise oil-water tension measurement. Essential for evaluating oil aging and detecting sludge formation risks.
Closed Cup Flash Point Tester
Features Dual Ignition (Gas/Electric) and automatic atmospheric pressure correction for maximum accuracy. Ideally designed for measuring flash points (40°C~370°C) of petroleum products with forced air cooling efficiency.
Karl Fischer Titrator
Uses the Coulometric Karl Fischer method to detect trace moisture at the ppm level. Essential for preventing insulation breakdown caused by water content in transformer oil.
Kinematic Viscosity Tester
Provides precise viscosity measurements with superior temperature control (±0.01℃). Accurately measures kinematic viscosity for engine, hydraulic, gear, and industrial oils.
