Home Our company Calibration laboratory

Calibration laboratory

Our measuring laboratories are located in Poland, in the production plant in Długołęka and in the headquarters of Günter GmbH in Schwaig near Nuremberg where, for over 20 years now, temperature sensors are calibrated. In 2014 an important milestone has been reached when DAkkS (Deutsche Akkreditierungsstelle) accredited our calibration laboratory. The accreditation gives us the possibility to also perform calibrations according to official DAkkS standards.

The accreditation applies to the calibration of resistance thermometers and thermocouples in the temperature range of -80 °C to +1500 °C. The accreditation indicates that we use standardized measuring methods and that the calibration equipment is under constant control, in which all the reference elements and instruments are recalibrated annually by a higher certified laboratory.

What is DAkkS?

DAkkS is the national accreditation agency of Germany. In the past Germany had multiple accreditation agencies for different kind of aspects like temperature, pressure, weight and such, but after January first 2010 these agencies were joined together in a new European Regulation. DAkkS has a legal mandate for the accreditation of conformity assessment agencies (laboratory, inspection and certification agencies) and is the only service provider for accreditation in Germany. Accreditation gives an unbiased confirmation that an agency works competently and according to regulations.

DAkkS and factory calibrations

Calibration results are documented in a calibration certificate and the calibrated article gets a calibration tag. Depending on the customers wishes we can perform a DAkkS or a factory calibration. Factory calibrations can be performed in the temperature range -80 °C to +1550 °C. 

The advantages of calibrations according to DAkkS standards:

  • Very reliable calibration measuring results
  • Internationally accepted calibration results
  • Traceable to national and international standards
  • A high and consistent quality through external controls
  • Independent and regular certification of the laboratory and equipment
  • Calibration according to national and international standards and regulations

 

Measuring methods

Temperature sensors calibrated by comparison with a reference thermocouple or a reference resistance thermometer. Reference probes are periodically calibrated in independent, external accredited laboratories for fixed temperature values according to ITS-90 scale. The key condition for the comparison method is that the sensors, measurement and reference are under the same conditions, i. e. in terms of environment (medium), measured temperature and humidity and ambient temperature. For this purpose, special calibration furnaces are used, located in stabilised and climatically monitored rooms. Günther laboratories use dry block calibrators, tube furnaces and liquid thermostatic baths.
