Transformer Oil Oxidation Stability Tester LOST-D11 FAQ's
  • Labtron’s Transformer Oil Oxidation Stability Tester LOST-D11 is specifically designed to evaluate the oxidative stability of transformer oils and other petroleum products. By simulating long-term aging conditions under controlled temperature and oxygen flow, it helps determine how resistant the oil is to oxidative degradation. This information is critical for ensuring the long-term performance and reliability of transformers and other high-voltage electrical equipment that rely on insulating oils for cooling and insulation.

  • Our Transformer Oil Oxidation Stability Tester LOST-D11 allows the simultaneous testing of up to six different oil samples. Each test unit operates independently with its own flow meter and control system, enabling parallel testing without interference between samples. This significantly increases productivity, especially in laboratories and industrial settings where multiple sample analyses are conducted regularly.

  • Each of the six test units in our Transformer Oil Oxidation Stability Tester LOST-D11 is equipped with a dedicated flow meter that allows for individual monitoring and control of oxygen flow. The flow rate is adjustable and maintained at 17 mL/min ± 0.1 mL/min. This precise control ensures the accuracy of oxidation stability measurements and reduces variability between samples during testing.

  • Transformer Oil Oxidation Stability Tester LOST-D11 is widely used in petroleum refineries, electrical equipment manufacturing, and chemical industries. It is especially valuable in research and development laboratories where the aging characteristics of insulating oils are studied. This device ensures that transformer oils meet quality standards and can perform reliably under prolonged service conditions.

  • Labtron’s Transformer Oil Oxidation Stability Tester LOST-D11 combines precision control with high efficiency. Its ability to run six tests simultaneously, coupled with accurate digital control of temperature and flow rate makes it ideal for laboratories seeking dependable results with minimal manual intervention. Its compact structure, automatic timing, and user-friendly interface reduce human error and operational downtime, ensuring smooth workflows and dependable testing outcomes.
