TESTING SERVICES OIL ANALYSIS AFRICA OIL ANALYSIS AFRICA

Through oil testing and analysis, Intertek is able to analyze a wide range of oil based products. Supporting client oil condition and predictive maintenance programmes, our oil tests are performed to ASTM, ISO, IEC, IP, in-house, client, and other industry standards.

Oil Condition Monitoring Oil Testing The Solution Machinery requires planned maintenance Within a transformer, oil acts as an By predicting the condition of the transformer to perform optimally. The frequency of this and a coolant.
