Correct and reliable measurements are the prerequisites for any high-quality industrial production. Measuring and testing equipment is used, among other things, for the quantitative determination of properties as well as for controlling, regulating and automating production. Measurements are therefore an important part of industrial quality assurance, see also DIN EN ISO 9000 and 9001.
All equipment used for measurements, including equipment for auxiliary measurements, e.g. for ambient conditions, and having a significant influence on the accuracy and validity of the result of the test or sampling, must be calibrated before it is put into operation.
SIKA has been a member of the German Calibration Service (DKD) since 1995 and is accredited according to DIN EN ISO / IEC 17025. For over 25 years, we have actively contributed our experience to working groups and regularly participate in intercomparisons.

How often should I have my measuring equipment calibrated?
The frequency of calibration depends on the balance between risk and costs. The shorter the time between calibrations, the lower the risk of questionable measurements. We recommend having measuring instruments calibrated annually.
Temperature calibration service
Our calibration laboratory is accredited for the calibration of temperature block calibrators in the temperature range from -55°C to 1300°C. Resistance thermometers can be calibrated and certified in the range from -30°C to 660°C, and thermocouples in the range from -30°C to 1000°C.
The basis of every calibration is the International Temperature Scale of 1990 “ITS-90”, as well as the guidelines and standards currently used by the calibration laboratory. As far as the design permits, the calibration points for thermometers can be freely selected within the accredited range, so that the calibration covers the actual operating range as effectively as possible.
If you have any further questions regarding our calibration service, please feel free to contact us.
Pressure calibration service
The calibration laboratory for “absolute pressure and positive overpressure” allows the calibration of analog and digital pressure measuring devices and pressure sensors with an electrical output signal (e. g. 0...10 V, 4...20 mA, ...).
Calibration is carried out as a comparison measurement against a dead weight tester utilized as the reference standard. The dead weight tester is used to pressurize the instrument under test with a defined pressure from 1...1200 bar. Depending on the actual measuring range, the smallest possible measuring uncertainties are 0.7 mbar.
Each calibration is based on the guidelines and standards currently applied by the calibration laboratory.

Electric values calibration service
Resistors and ohmmeters can be calibrated from 0 to 2 kΩ. Depending on the resistance value, the smallest possible measuring uncertainty is 0.1 mΩ. DC voltmeters and transmitters can be calibrated between 0 and 20 VDC with a smallest possible measuring uncertainty of 2 μV. DC testing and measuring devices for standard signals (0)4...20 mA can be calibrated with a smallest possible measuring uncertainty of 0.05 μA.
Each calibration is based on the guidelines and standards currently applied by the calibration laboratory.
