Calibration Laboratory

Hydrotechnik operate a range of high quality test benches for calibrating flow, pressure, temperature and electrical parameters.


Measuring rangeRemarks
Flow rate of liquids0,005 … 1000 L/minMineral oil-based calibration fluids with viscosities between 1.5 … 300 cSt.
Pressure-1 … 1200 barGas or mineral oil pressure media
Temperature-50 … 250 °CImmersion sensors
Current0 … 20 mAFor Hydrotechnik’s measuring systems
Voltage-10 … +10 VFor Hydrotechnik’s measuring systems
Frequency0 … 20000 HzFor Hydrotechnik’s measuring systems


All measured variables and sensors for recording the environmental conditions are traceable back to national standards.

Depending on the measurement quantity and required measuring range, the customer can choose between accredited procedures and factory calibration procedures.

Calibrations according to accredited procedures

For the measurement and certification of liquid flow and pressure, Hydrotechnik provides a complete calibration service according to procedures accredited by the Deutsche Akkreditierungsstelle (DAkkS). The laboratory conforms to the specifications of DIN EN ISO / IEC 17025 with procedures and processes regularly assessed by DAkkS.

The scope of accreditation can be found in the annex to the accreditation certificate.

DAkkS is a signatory to the multilateral agreements for mutual recognition of the European cooperation for Accreditation (EA), the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC). The signatories to these agreements recognize each other's accreditation body. Therefore, calibration certificates that certify a calibration according to a DAkkS-accredited procedure are internationally recognized.
