Lube oil checks and recommended testing kits
For field inspection of lube oils, the following points are important to take action:
- Lube oil basic tests are visual inspection in a glass sample bottle for colour.
- A common test involves the use of hand-held testing kits, which are not complex and are very easy to use at the site. If the colour of lube oils is found to be milky or a dark shade, you have to go for further testing/procedures.
The following are the testing kits that can be used at the site for checking lube oil:
- Millipore Patch Testing Kit –This kit is used for determining oil contamination according to the NAS/ISO by observing the patch paper with a microscope. This is a very basic test to check whether the oil is dirty or clean. A portable patch testing kit and also handy for working around the site.
- Hydrogauge Oil Test Kit – Qualitative moisture or water contamination in oil test, adding 10 ml of sample into 2 types of different reagents. This is another cost-effective & offline testing kit which delivers approximate results.
- Visgauge Oil Test Kit – Visgauge Oil Test Kit. It is handy to check the viscosity of oils in the 0 to 460 range of oils. Simply put, this testing kit doesn't require any proficiency and is portable.
- Online Laser Particle Counter – This is an inline contamination monitor capable of measuring oil contamination in NAS, ISO format, with particle distributions in 8 Nos of channels. The particle counter can be connected with a pipeline or any outer oil filtration system, with the feature of reducing pipes and has an LED screen to display the results as well.
- Introduction Portable Online Laser Particle Counter: It is a portable online contamination monitor widely used for oil contamination monitoring in NAS, ISO format, with particle distributions in 8 Nos of channels. This particle counter can verify NAS values over different sample types or over different machines. The particle counter has an indication of minimum hoses in Advance, provides a connection with the pipeline or any external oil filtration unit and an LED Screen to display results.
