Oil viscosity measurements play a critical role in determining lubricating oils' usability and quality. Excessively high viscosity leads to poor lubrication, excessive friction, and high power consumption. Excessively low viscosity causes an excessively thin oil film between moving parts, causing catastrophic failure. Each lubricating oil is therefore designed to have an optimal viscosity, within a specified range for each application.
Typical practice is to send oil samples extracted from the machinery to off-site laboratories for viscosity measurements — which can take days, if not weeks. Such an infrequent and delay in viscosity results can lead to missing the opportune time for oil exchange, which can cause machinery or compressor breakdowns resulting in significant down time and financial losses.
