We are full-service providers in plant and test bench construction. Our focus is on flow, volume flow and mass flow measurement, temperature, pressure & humidity control or measurements of small gaseous quantities as well as high pressure testing. Our calibration laboratory is DAkkS accredited (according to DIN EN ISO / IEC 17025 for volume and mass flow of flowing gases). We also offer factory calibrations of the measured variables temperature, humidity, absolute pressure, differential pressure and relative pressure.
