DAkkS-accredited calibrations

Our calibration laboratory is accredited by the German Accreditation Body (DAkkS) in accordance with the DIN EN ISO/IEC 17025 standard under DAkkS registration no. D-K-17589-01-00.
The measured variables are volume and mass flow or volume and mass of air and gases as well as the variables pressure, temperature, relative humidity and electrical DC voltage, DC current and DC resistance. TetraTec Instruments is also a member of the relevant technical committees of the German Calibration Service (DKD) under the supervision of the Physikalisch-Technische Bundesanstalt (PTB).
