Lubrication Oil

​​All machines with lubricating oil systems can benefit from the monitoring of moisture content in the oil. Water deteriorates oils performance, whether used as a lubricant, coolant, insulator or for other purposes. High moisture content increases the risk of corrosion, overheating, machine malfunctions and other costly problems. Vaisala's unique moisture in oil measurement monitors the water activity of the oil continuously and online, which directly indicates the margin to free water formation in the oil. Unlike traditional sampling methods, which can take days or weeks to produce test results, Vaisala's continuous measurement ensures reliable equipment performance at all times.
