1. Power industry:
Insulation oil (transformer oil, cable oil): Evaluate its purity and aging degree, prevent the formation of oil sludge inside transformers and cables, and ensure the safety of the power grid.
2. Lubricating oil industry: industrial lubricating oil, engine oil: researching the formula of lubricating oil, evaluating its oxidation and pollution during use, ensuring lubrication effect and equipment life.
3. Petrochemical industry: crude oil, distillate oil, surfactants: used for research on crude oil recovery, monitoring of oil refining processes, and performance evaluation of surfactant products.
4. Research and testing institutions: new materials, academic research, third-party quality arbitration: used for basic research in surface chemistry, or as an authoritative third-party for product quality identification.
5. Electronics and Semiconductors:
Electronic Fluorinated Liquids, Cleaning Agents: Ensure high purity and specific surface tension, used for precision circuit cleaning and cooling to prevent residue.

2.Using new and improved magnetic tank enclosed electromagnetic force balance sensors, improve the response speed and linearity;
3.New sensor calibration point can only solve the previous generation sensors require multi-point calibration to ensure the accuracy of the linear problem, replacing the zero potentiometer and span potentiometer adjustment, to make it more stable and reliable;
4.Using a sine wave oscillator Wien Bridge-precision high-speed operational amplifier, with little distortion, easy debugging features.

 

 

1. Temperature: Stable room temperature (such as 20-25 ℃ C).
2. Humidity: Relative humidity is below 80%.
3. Location: A stable experimental platform without vibration, strong airflow, or strong electromagnetic interference.

 

  • must be absolutely clean and free of grease contamination.
  • : It needs to be transparent and free of suspended particles. If there are particles, they need to be filtered.
  • : Use freshly prepared high-purity water.

 


: Before use, it must be thoroughly burned on an alcohol lamp flame until red hot to remove any organic pollutants.
Regularly use standard weights or standard liquids of known weight for calibration.
Ensure that the instrument base is completely level.

A:It is employed to precisely measure the interfacial tension between transformer oil and water. This value enables assessment of the oil's purity and℃of ageing, preventing sludge formation and ensuring transformer safety.

Q: .Why measure 'interfacial tension'?

A:Interfacial tension serves as a 'health indicator' for transformer oil. High tension in new oil signifies purity; a sustained decline indicates ageing and the formation of harmful impurities, acting as an early warning for potential faults.

A: The procedure is straightforward, but the most crucial step is ensuring absolute cleanliness! The sample cup and the vital platinum ring must be thoroughly cleaned.

A:Yes. Testing must be conducted on a stable, vibration-free laboratory bench. Avoid draughts, temperature fluctuations, and vibrations, as these factors can disturb the liquid interface and compromise measurement accuracy.

A: From preparation to completion, a single test typically takes approximately 10-15 minutes. This encompasses cleaning, sample addition, interface stabilisation, and measurement time.


A: Adherence to standards (e.g., ASTM D971) is required. Generally:
> 40 mN/m: New oil or oil in excellent condition.
35 - 40 mN/m: Oil quality beginning to deteriorate, requiring monitoring.
< 35 mN/m: Significant oil degradation with risk of sludge formation, necessitating prompt action.
