Determining water levels in lubricating oils

It is impoirtant to determine the presence of water in machinery lubricating oils, which is why Metrohm is offering its 831 KF Coulometer to give reliable results over a long period.

Metrohm said that moisture is considered a chemical contaminant when suspended or mixed with lubricating oils.

It presents a combination of chemical and physical problems for the lubricant and machinery, respectively.

Failure due to water contamination may be catastrophic, but it may not be immediate.

Many failures blamed on lubricants are truly caused by excess water, said Metrohm to manufacturingtalk.

Some of the effects of water on equipment include the following.

* Shorter component life due to rust and corrosion.

* Water etching/erosion and vaporous cavitation.

* Hydrogen embrittlement.

* Oxidation of the bearing.

* Wear caused by loss of oil film or hard water deposits.

The level of water in these matrixes needs to be determined quickly and accurately, said Metrohm.

Metrohm said that its 831 KF Coulometer has proven time and time again to be excellent for the determination of these very small amounts of water.

Improved coulometric generator cells and reagents ensure an interruption-free operation and reliable results over a long period.

The 831 KF Coulometer has two principle working modes.

1 - The expert mode allows it to use all different features of this high tech device.

2 - The standard mode needs just a few keystrokes to start your analysis.

All unwanted keys can be locked out securely.
