Calmet Calibration Laboratory

  Certyfikat Akredytacji

Calmet Calibration Laboratory offers calibration of measuring instruments in the field of all parameters of the multiphase voltage and current vector. We calibrate all types of instruments that measure (meters, electricity meters, and quality analyzers) or generate electricity values (calibrators). For more information, please see our full range of services.

We have over 30 years of experience in designing and production of standards of power network parameters and power quality. We calibrate our devices using the highest class of accuracy class and quality standards with traceability to the National Standards Institutes. In the production of standards, we have introduced automation of the measuring procedures which resulted in the minimization of the need for operator participation in the measurement process thus minimizing the subjective factor and increasing the reliability of the measurement results recorded in the certificate of calibration. An additional advantage of automation of the calibration process is the ability to reduce calibration costs computed on each measuring point.

Our measuring stations and automated procedures are used to provide calibration services of instruments (manufactured by us or other companies) held by our clients. Our calibration scope incudes values such as: DC voltage, DC current, AC voltage, AC current, DC resistance, phase shift angle, AC energy, AC power, time (time interval), and frequency.

To ensure a high quality of service, we have implemented a system compliant with the PN-EN ISO 9001:2015 and PN-EN ISO/IEC 17025:2018-02 standards and confirmed the fulfillment of the standards by obtaining the Certificate of the Calibration Laboratory No. AP 216 issued by the Polish Centre for Accreditation.

We offer calibration services for: power quality analyzers, electricity meters, devices for testing electricity meters, calibrators, and clamp meters in all accuracy classes in the scope of accreditation with CMC for Power and Energy at the level 0.007%.
