JCKW-C Handheld Oil Analyzer

Oil Analyzer

By introducing a very high-frequency alternating current waveform, we can accurately measure the oil’s ability to store energy (capacitance) and conduct electricity (conductance). This allows us to assess the depletion of lubricant additives, the degree of acidification, oxidation, and aging of the oil, as well as contamination levels, thereby providing a basis for condition-based maintenance.

Analysis of the curve shows that the conductivity values exhibit high sensitivity to contamination in the oil.

Tests on Castrol lubricants sourced through various channels have shown that even oil that appears clean can have significant quality issues; oil quality sensors can distinguish between recycled, filtered used oil and genuine, original lubricants.

The primary standards referenced are GB/T 7597-2007 “Sampling Methods for Electrical Insulating Oils (Transformer Oil, Turbine Oil)” and NB/T 1011-2018 “Operational Testing Procedures for Lubricants in Wind Turbine Generators,” both issued by the National Energy Administration.

Testing items include: Physical and chemical properties: viscosity, acid value, moisture content, dielectric constant, etc.; Sampling frequency: Generally recommended once every 3–6 months

Basic Testing Package: If only basic items such as viscosity, acid value, and moisture content are tested, the cost is generally between 200–5,000 RMB per test.

Sampling and testing results: 95% of oil samples are normal; that is, economic loss: 95% of the cost

Electrochemical Impedance Spectroscopy (EIS) technology is used to measure the impedance spectrum of lubricating oil. By analyzing changes in impedance spectrum parameters, this method evaluates the depletion of lubricant additives, the degree of oil aging, and contamination levels, thereby providing a basis for condition-based maintenance.
