Oil Analysis is termed as one of the key aspects of preventive and lubrication maintenance of any rotating equipment. This is because the oil mix-up contributes to machine failure, the most devastating and common problem which industry managers face. The reliability of any machine can be increased easily by making sure to put the perfect lubricating oil inside the machine. But to do this, the oil needs to be sent to offsite laboratories which involve cost investment along with wastage of time. This can be diminished with the help of on-site oil analysis which will boost up machine up-time and productivity.
