WHAT DO WE DO?
The Testing and Calibration Laboratory of SONEL S.A. offers calibration services for measuring instruments of both electrical and non-electrical values. Apart from standard calibration procedures, the laboratory is distinguished by the knowledge of Sonel products products in the scope of construction, time drift, etc. It enables the development of an optimal process of metrological verification, allowing to check the instrument in the wider possible range of its functionality and in the typical points for a given measurement.
To provide a high quality of services, we have implemented a management system compliant with the requirements of EN ISO/IEC 17025 standard “General requirements for the competence of testing and calibration laboratories.” We confirmed compliance with all the requirements of the standard by obtaining the Accreditation Certificate of Calibration Laboratory No. AP 173 issued by the Polish Centre for Accreditation in 2017. In the following years, we successively extended the scope of our accreditation to other areas. In terms of the number of performed calibration procedures, we are one of the largest laboratories of its kind in Poland. Over 25 years of experience and development allowed us to introduce to our offer services unique on the market. As one of the few laboratories, we can calibrate multifunction meters in a full range of functionality with accreditation.

We are distinguished by the implementation of calibration of measuring instruments in the scope of accreditation of:

impedance and short-circuit loop resistance meters from the value of 100 mΩ (including high-current fault loop impedance meters). As one of a few companies, we have a test power network with a dedicated transformer. Measurements are performed the power network, which allows omitting imperfections and limitations of methods based on simulations.
insulation resistance meters and standards in the range up to 15 kV and 20 TΩ and standards up to 40 TΩ at voltage up to 1 kV. This service is unique in the world.
small resistance meters for measuring currents from fractions of mA to several hundred amperes.
Our Laboratory forms a team of qualified specialists, for whom the quality of provided services is of the highest value.
USE OUR KNOWLEDGE AND EXPERIENCE!
OUR OFFER
We calibrate devices:
for measuring electrical values and parameters of power networks
meters: voltage, current, residual current protection, insulation resistance, earth resistance, short circuit loop impedance measurement, resistance, network parameters, multimeters
electrical standards
calibrators, resistance standards
for measurements of non-electrical values
pyrometers, lux meters, thermal imaging cameras
Most of the calibrations of the SONEL S.A. instruments is performed based on the standard calibration procedures.

We can provide an individual approach to the calibration process. Indicate the ranges and measurement points and we will prepare an offer tailored to your requirements.

DON'T YOU HAVE A SONEL DEVICE?
IT'S NOT A PROBLEM FOR US!

Within the scope of accreditation we calibrate
also meters of other manufacturers:

Fluke, Chauvin Arnoux, BRYMEN, Gossen Metrawatt, Metrel, UNI-T, HT Italia, Kyoritsu, Megger, Hioki, CEM, Flir et al

Check if your meter from another manufacturer is on the list.

If not, please contact us: [email protected]

The scope of calibration will be determined individually

CALIBRATION
Every meter that reaches us is important to us and we treat each one with the utmost care.
The calibration process consists in comparing the indication of the calibrated instrument with the indication of the reference instrument. The reference instrument is much more accurate than the calibrated instrument. However, the calibration results along with their uncertainties are presented in the calibration certificate.
Let's summarize. The whole process looks like this.
1.
Send order form on website
2.
Deliver the instrument using available methods
3.
Confirm the terms of the order sent by e-mail (optional)

When to calibrate?
SONEL S.A. recommends performing calibrations at least every 12 months for its instruments.
Why regular calibration?
See examples
Read
For brand new instruments put into service, the next performance confirmation is recommended to be carried out within 12 months from the date of entry into service (date of purchase), but no later than 24 months from the date of the first check. The next inspection is carried out by the Testing and Calibration Laboratory of Sonel S.A., and the issued document is called Calibration Certificate (instruments having the character of a standard) or Declaration of Verification (indicators, testers without the character of a standard).
The meters are calibrated at SONEL S.A. headquarters, at str. Wokulskiego 11, 58-100 Świdnica, Poland.
Only an actual calibration certificate certifies the metrological properties of a calibrated measuring meter!!
In the case of meters used for testing relating to protection against electric shock, the person carrying out the measurements shall have all confidence in the performance of the device used.Measurements made with an inoperative meter may contribute to an incorrect assessment of the effectiveness of protection health and even human life.
CALIBRATION CERTIFICATES
with PCA accreditation are recognized worldwide
This document defines the relationship between a standard and an indication of a meter and states the uncertainty of measurement.
The competence of the Testing and Calibration Laboratory of SONEL S. A. has been confirmed by an independent third party. Calibrations are performed according to standard procedures or based on individual customer requirements. The laboratory shall use methods of direct or indirect comparison to a standard, which are described in internal instructions.
