What Oelcheck does

OELCHECK GmbH is a privately held, 100% family-owned laboratory services company headquartered in Brannenburg, Upper Bavaria, Germany. Founded in 1991 by Barbara and Peter Weismann under the original name WEARCHECK and rebranded to OELCHECK in 2009, the company operates a 101-250 employee organization that is currently led by authorized managing directors Paul Weismann and Petra Bots.

The company's core business is the laboratory analysis of oils, lubricants, coolants, and other operational fluids drawn from industrial and commercial equipment. OELCHECK offers customized all-inclusive analysis sets tailored to specific component types — including engines, hydraulics, gearboxes, transformers, turbines, compressors, heat-transfer systems, and refrigeration equipment — using established analytical methods such as ICP-OES spectroscopy, FTIR spectroscopy, Karl-Fischer titration, and particle counting. These services are delivered through a direct-to-customer digital stack comprising the LAB.REPORT customer portal for online sample submission and report management and the OELCHECK App 4.0 for mobile workflows, supplemented by sampling accessories sold via an e-commerce shop. Complementary offerings include the OilDoc Akademie for training, an extensive Wiki knowledge base, and a CO2 calculator that frames lubricant analysis in sustainability/ESG terms.

OELCHECK serves a diversified European B2B customer base spanning energy generation (including wind turbines and gas engines), earthmoving and construction, machinery and plant engineering, transportation, automotive, petrochemical, lubricant suppliers, and maintenance/service contractors, with private users as a smaller tail. The go-to-market is primarily sales-led direct, with pay-as-you-go per-sample pricing in the home market and an exclusive-agent distribution model extending the offering into international markets outside Germany. Revenue is generated across three streams: per-sample laboratory analysis services, one-time sale of analysis sets and accessories, and recurring digital platform subscriptions — though no public financial figures are disclosed.
