Who are we?

European Lab Services (ELS), the specialized calibration and service department of the Optimus Instruments Group, is a brand-independent service partner for laboratories and industrial environments. Our mission is simple: to provide you with certainty and confidence in your measurement results. We guarantee the accuracy, compliance, and reliability of your laboratory equipment, so that you can focus on your research, quality, and production without worry.

Our Core Activities

To guarantee that your processes run flawlessly and meet the strictest ISO standards, we offer a comprehensive package of services:

Calibrations

We perform ISO/IEC 17025-accredited calibrations for all your laboratory and measuring instruments. This ensures the precision and traceability of your measurements.

Verifications & Validation

ELS provides on-site ISO 17025 verifications of laboratory and industrial equipment (including petroleum testing equipment). Thanks to our flexible accreditation scope, we can even develop custom-made, certified test procedures for unique or new applications.

Maintenance & Repair

We maximize the uptime and lifespan of your instruments through customized preventive maintenance programs. In the event of unexpected breakdowns, we provide fast, corrective repairs. Because we maintain an extensive stock of spare parts and work with certified technicians, we guarantee minimal downtime.

Installation & Training

Beyond the install: we not only install new equipment, but also train your employees. This ensures that your equipment is operated accurately and in accordance with regulations.

Sectors and Scope

Our certified engineers possess broad expertise in sectors such as petrochemicals, life sciences, the packaging industry, and construction.

Thanks to our strategically located offices in Belgium (Sint-Niklaas and Deerlijk), the Netherlands (Barendrecht/Rotterdam), and France (Caen), we are always close to our clients in Western Europe. We also offer comprehensive Service Level Agreements (SLAs) tailored for multi-site laboratories. This streamlines planning, ensures consistent maintenance across all sites, and improves the reliability of inter-laboratory comparisons.
