3 SERCAL, S.L. (SC LABORATORIO DE CALIBRACIÓN)

3 SERCAL, S.L., trading under the brand SC Laboratorio de Calibración (and commercially as SC Servicios Tecnológicos), is an independent calibration and metrology laboratory headquartered in Castellón de la Plana, Spain. Founded in 2006 and operating from its facility at C/ Amalia Abad Pastor, Nº 1, Polígono Industrial la Basala, the laboratory has built close to two decades of experience providing precision measurement and calibration services to industrial clients across Spain and Portugal. The company operates with a small, highly qualified team dedicated to ensuring that customers' measurement and test equipment performs within specified tolerances, thereby helping those clients satisfy the requirements of quality certifications and regulatory audits.

The laboratory's core offering is the calibration of a broad range of measurement magnitudes and the instruments that measure them. In the area of mass (masa), SC Laboratorio calibrates single-pan balances and precision scales of all capacities, a scope for which the laboratory holds formal accreditation. In the electrical domain, it calibrates data loggers, ammeters, voltmeters, multimeters, and process calibrators. For temperature, the laboratory handles thermometers, temperature probes, industrial ovens, climatic and thermal chambers, and infrared pyrometers. Dimensional and length calibration covers dial indicators, Vernier calipers, micrometers, and gauge blocks (patrones de longitud), while pressure calibration extends to manometers, pressure transducers, and pressure transmitters.

Beyond those primary areas, the laboratory also calibrates force gauges, torque wrenches, and hydraulic presses in the force domain, as well as thermocouples, Pt100 resistance temperature detectors (RTDs), and industrial transmitters in the instrumentation domain. Additional measurement instruments serviced include gas analyzers, lux meters, viscometers, pH meters, and conductivity meters — a breadth that reflects the diverse analytical needs of its client base. All calibration work is performed in compliance with a quality management system founded on UNE-EN ISO/IEC 17025, with uncertainty calculations following the ENAC guidance document EA-4/02 M:2010, and procedures aligned with the methodology established by Spain's Centro Español de Metrología (CEM).

SC Laboratorio de Calibración holds accreditation from ENAC (Entidad Nacional de Acreditación), Spain's national accreditation body and the country's single multilateral recognition signatory under the EA (European co-operation for Accreditation) and ILAC frameworks. The laboratory's ENAC accreditation under ISO/IEC 17025 for the mass area — covering single-pan balances and scales — has been in force since April 2009, establishing its long-standing competence in metrological traceability. Non-accredited calibrations performed by the laboratory are nonetheless conducted under the same ISO/IEC 17025-based quality management system, giving clients a consistent standard of reliability across all service areas. Staff qualifications, supervision, and periodic recertification follow the personnel competence requirements set out in ISO/IEC 17025.

The laboratory serves a notably diverse set of industrial sectors, with a particularly strong presence in the ceramics and building-materials industries of the Valencia Region — one of Spain's most concentrated manufacturing hubs for ceramic tiles and construction products. Documented clients include internationally recognised tile brands such as Grespania, Porcelanosa, Pamesa, Vives, and Marazzi, as well as construction materials suppliers Kerakol and Macer, and chemical-products manufacturer Quimialmel. Beyond ceramics and construction, SC Laboratorio serves food and alimentary-sector companies, pharmaceutical and chemical-process industries, and general manufacturing clients throughout Spain and, to a growing extent, Portugal.

Service delivery is designed around speed and convenience. The laboratory offers both in-house calibration at its Castellón facility and on-site calibration at the client's premises, minimising equipment downtime and reducing logistical complexity for plant managers. Calibration certificates are typically issued and delivered digitally via a secure client portal within one week of the service date. The laboratory also offers customised training sessions in metrology and calibration practice, helping client quality teams build internal competence and better manage their calibration programmes in accordance with ISO 9001, IATF 16949, and other sector-specific management system standards.

As a member of the Red de Laboratorios de la Macaronesia (Macaronesia Laboratory Network), SC Laboratorio de Calibración extends its reach beyond mainland Spain, offering its calibration expertise to clients in the Canary Islands and other Atlantic island territories where access to accredited metrology services can otherwise be limited. The laboratory has additionally benefited from EU NextGenerationEU funding to modernise instrumentation and strengthen its quality infrastructure. For manufacturers, food processors, tile producers, and chemical companies whose ISO or customer audits demand demonstrably traceable, independently verified measurement data, 3 SERCAL, S.L. offers a regionally established, ENAC-accredited partner with the responsiveness and technical depth that larger national providers often cannot match at the local level.
