Smoothing the way
While many new developments now allow lubricant quality to be monitored continuously in situ - as well as various kits and portable equipment that enable tests and measurements to be carried out on site - it is still general practice for samples to be taken and sent off for analysis. The alternatives are to have a system that keeps pumping fresh lubricant to wherever it is required - backed up by analysis to determine how much needs to be pumped in and how often - or to design out the need for lubrication altogether.
