Geserco, European pioneer in used oil analysis
GESERCO, 50 years of service and innovation
In 1973 GESERCO invented the concept of “Portable Oil Testing Kit” which allows any user in the field, where the machinery is operated, to instantly monitor the condition of oils and fuels without the need for sending a sample to a laboratory.
Through some very simple, rapid and cost effective techniques, the GESERCO oil test kits give operators and maintenance personnel and advance warning of potential machinery failures, avoiding costly breakdowns, reducing operational expenditures and protecting industrial assets.
The GESERCO test kits are applicable to engine lubricating oils, turbine oils, gear oils, hydraulic oils, biodiesels, fuels, metal machining fluids...They come with a comprehensive operation and interpretation user guide allowing any user, even a non-specialist, to make immediate on-site decisions for maintaining and safeguarding the lubricated equipment.
Over the past 50 years certain GESERCO tests have become industry standards in the marine, automotive, aircraft and industrial fields... Some have even been standardized by ISO.
Please browse our website and read on to discover how and why 30 000+ industrial sites worldwide are using the GESERCO technology and how our rapid oil test kits can help you!
We look forward to teaming up with you!

Over time, heat, oxidation, and contaminants gradually reduce a lubricant’s properties. One of the best indicators of this degradation is the Total Acid Number (TAN). Why is it important to monitor TAN? When oil acid number increases, it o...
Monitor lubricant trends, not just snapshot results!
When analyzing a lubricant, the measurement itself is important. But what truly counts is how the results change over time. A slightly out-of-range value may be acceptable… A rapidly deteriorating value can be critical, even if it is stil...
