What GESERCO does
GESERCO SAS is a privately-held French industrial manufacturer founded in 1973 and headquartered in Le Haillan (near Bordeaux). The company designs, manufactures, and sells portable test kits and instruments that enable non-specialist operators to perform rapid, on-site analysis of lubricants, fuels, and related fluids without sending samples to a laboratory. Its product range covers more than 20 test parameters — including Total Acid Number (TAN), water content, viscosity, BN-TBN, particle content, iron content, dilution, and flash point — across 2,000+ oil references, delivered through products such as the OCMS™ Oil Condition Monitoring System, DPOT™ Digital Precision Oil Tester, FlashTest™ C, and the Viscobille™ viscosity series, plus consumable spare packs and specialized kits for marine, aerospace, defense, and rail applications.
The company earns revenue through three streams: one-time hardware sales of test equipment and kits (with 100% prepayment at order confirmation, EXW Le Haillan), recurring sales of consumables, reagents, and spare parts that create an installed-base annuity, and ancillary professional services such as training and installation. Go-to-market is sales-led, combining a multilingual direct website (FR/EN/ES/DE/IT) and major international trade shows (Sea Japan, SMM, Lubricant Expo, Lab Italia) with a global distributor network of 40+ partners across more than 40 countries on five continents, which delivers 85% of revenue from exports.
GESERCO claims over 30,000 industrial sites equipped worldwide, a 25% annual growth rate, "Number 1" European market position in lubricant condition monitoring, and conformance of key products to ASTM D92, IP 36, and ISO 2952 standards. ISO 9001:2015 certification was obtained in 2026. The customer base spans maritime, automotive, aerospace, defense, energy, mining, cement, rail, and general industry, with named brand references including AREVA, MOTUL, BP, REPSOL, SHELL, LUBRIZOL, INFINEUM, SNCF, and Goodrich.

GESERCO competitors and assessment
Company assessmentDirect peers
- Spectro Scientific (AMETEK): Spectro Scientific, owned by AMETEK, manufactures portable and laboratory oil condition monitoring instruments including spectrometers and fluid analysis systems directly competing with GESERCO's OCMS™ and DPOT™ product lines for in-service lubricant analysis.
- Kittiwake (Parker Hannifin): Kittiwake (now part of Parker Hannifin) provides on-site oil condition monitoring kits and sensors for marine and industrial applications, overlapping directly with GESERCO's field-portable testing kits and maritime-focused product offerings.
Emerging players
- Tan Delta: Tan Delta develops real-time oil condition sensors and digital monitoring technology for industrial machinery, providing an emerging IoT alternative to GESERCO's portable manual test kits in predictive maintenance applications.
Broad incumbents
- AMETEK: AMETEK is the parent of Spectro Scientific and a broad industrial instrumentation conglomerate with significant R&D and global sales coverage, operating adjacent analytical and test equipment lines that overlap with GESERCO's product portfolio.
- PerkinElmer: PerkinElmer is a large analytical instrument manufacturer offering laboratory and field spectroscopy, chromatography, and fluid analysis systems that overlap with GESERCO's industrial lubricant analysis market.
- Anton Paar: Anton Paar manufactures high-precision laboratory and process instruments for viscosity, density, and flash point measurement — directly adjacent to GESERCO's Viscobille™ and FlashTest™ product lines but at the lab-grade end of the market.
- Hach (Danaher): Hach, part of Danaher, manufactures water and fluid quality testing instruments with industrial and field-deployable product lines that overlap thematically with GESERCO's water contamination and fluid testing kits (WaterTest™, GoTest™).
Others
- SGS: SGS is a global testing, inspection, and certification company that operates lubricant and oil analysis laboratories serving the same industrial, maritime, and oil & gas customer base that GESERCO addresses with portable kits.
- Bureau Veritas: Bureau Veritas operates oil and fuel testing services for maritime, oil & gas, and industrial clients, providing a service-based alternative to GESERCO's portable in-house testing approach for lubricant condition monitoring.
- Intertek: Intertek runs global petroleum and lubricant testing laboratories serving oil & gas, transportation, and industrial customers — competing for the same end-user maintenance budgets as GESERCO but via outsourced laboratory testing rather than portable kits.
