We can even carry out the corrective actions for you if required, ensuring confidence that they have been undertaken correctly.

Operating Temperature

A visual assessment of the machine sump and sample will give a good indication of fluid condition.


A refractometer is the ideal tool for shop floor checks on single sump machine, the reading should be sharp. If blurred, then there may be tramp oil or stability problems.

Dirt/Fines Levels

Dirt / Fines to be at minimal levels dependant on the application.

pH Measurement

pH gives a good indication of fluid condition.

  • Bacteria and fungi produce acids which reduce emulsion pH

  • A sharp drop in pH usually means an increase in bacteria levels

Tramp Oil

Current HSE Guidance states a maximum 2% volume for tramp oil.

Monitoring Microbial Contamination

Dip slides are cost effective and simple easy to use. They tell us the level of contamination so we can determine corrective action. HSE requires testing to be weekly minimum. (* can be extended)


To ensure machine and parts do not corrode.
