Polytest Laboratories provides testing services for various types of oils, including lubricating oils and hydraulic oils. By testing these oils regularly, machine operators can detect potential issues early and prevent machine breakdowns, which can save time and money on repairs and downtime. Lubricating oil testing typically involves analyzing the oil's viscosity, acidity, and contaminants such as dirt, metal particles, and water. Hydraulic oil testing may include checking for the presence of water, contaminants, and degradation products, as well as measuring the oil's viscosity and acidity. Polytest Laboratories may use a range of techniques to test oils. The results of these tests can help operators determine whether the oil needs to be changed, and if so, when it should be changed. Regular oil testing and maintenance can help prolong the life of machines and reduce the risk of unexpected breakdowns, which can lead to lost productivity and increased costs.
