CALTEX SISTEMAS

CALTEX SISTEMAS is an ENAC-accredited calibration laboratory based in Spain, operating under accreditation number 159/LC10.115 and governed by ISO/IEC 17025—the international benchmark for the technical competence of calibration and testing laboratories. Founded in 2003, the company has built more than two decades of specialist expertise in industrial metrology, positioning itself as a comprehensive, single-source provider for instrument calibration across a wide range of physical quantities. With ten laboratories accredited by ENAC (Entidad Nacional de Acreditación), Spain's national accreditation body, CALTEX issues calibration certificates that carry full national and international validity, enabling clients to demonstrate traceability of their measurements to primary national and international standards.

The core competency of CALTEX is the calibration of industrial measurement instruments across an extensive portfolio of physical magnitudes. The laboratory's ENAC-accredited scope covers Temperature, Masses and Weighing (pesaje), Relative Humidity (humedad relativa), Hardness (dureza), Force and Torque (fuerza y par), Pressure (presión), Dimensional (dimensional), Volume (volumen), and Electricity (electricidad). Beyond its accredited scope, CALTEX also offers calibration services in the areas of Time and Frequency (tiempo y frecuencia), Chemistry (química), and Optics (óptica), giving clients a single-stop solution for virtually all measurement disciplines encountered in modern manufacturing and process environments.

Caltex provides both laboratory-based calibration and on-site (in situ) calibration services, allowing companies to have their instrumentation verified at the point of use without the operational disruption of transporting equipment off-site. The mechanical calibration department holds ENAC accreditation for mass calibration since 2009 and is equipped to certify masses classified according to OIML (Organisation Internationale de Métrologie Légale) requirements, as well as standard masses and mass patterns of any nominal value up to 30 kg. The dimensional calibration capability covers length, geometry, and form measurements, while the force and hardness laboratory addresses calibration of load cells, torque wrenches, and hardness testers across scales including Rockwell, Vickers, and Brinell.

Caltex serves a broad cross-section of industry, transferring metrological traceability to sectors including agri-food (agro-alimentario), automotive, aeronautical, energy, pharmaceutical, medical devices, and general industrial services. Clients depend on CALTEX's calibrated measurement data to satisfy regulatory requirements, maintain quality management certifications such as ISO 9001 and ISO 13485, and ensure the reliability of process control and product inspection equipment. The laboratory counts blue-chip manufacturing and process companies—including clients such as Coca-Cola, Bayer, and Repsol—among its customer base, a testament to the trust the Spanish industrial sector places in its work.

The distinction between an accredited laboratory (laboratorio acreditado) and a merely certified one is central to CALTEX's value proposition. ENAC accreditation, unlike ISO 9001 certification alone, involves direct technical assessment of the laboratory's measurement methods, uncertainty budgets, reference standards, and staff competence by peer-review assessors. This means calibration certificates issued by CALTEX carry the ENAC mark and are recognized under the multilateral agreement of EA (European co-operation for Accreditation) and ILAC (International Laboratory Accreditation Cooperation), making them accepted by regulators and auditors throughout Europe and beyond. The laboratory publishes its accreditation certificate and full accreditation scope for download, ensuring full transparency about the instruments, measurement ranges, and best measurement capabilities covered.

In addition to its core calibration services, CALTEX offers tailored training courses in metrology and calibration-related topics—described as 100% practical and designed around the needs of each client. These courses cover subjects such as expanded measurement uncertainty (incertidumbre expandida), the difference between accredited and certified laboratories, and calibration management fundamentals, enabling clients to improve their internal understanding of metrological requirements. The training activity is noted as falling outside the accredited laboratory scope but forms part of the company's broader commitment to client capability development.

Caltex operates a technology partnership with Femto Instruments (www.femto.es), through which clients can purchase new measurement instruments that already carry an ENAC-backed CALTEX calibration certificate—eliminating the lead time between instrument delivery and first productive use. This end-to-end service model, covering instrument supply, initial calibration, periodic recalibration, and operator training, reflects the company's strategic positioning as a complete metrology solutions centre (centro de soluciones relacionadas con la Metrología y la Calibración). Companies seeking a calibration partner that combines ENAC-accredited technical authority, in-situ service flexibility, a broad measurement scope, and an established track record of serving major industrial clients will find CALTEX a highly credible and capable choice.
