DAkkS-akkreditiertes Kalibrierlabor

June 2017 DAkkS Accreditation with New Quantities

The extension of the existing measurement quantity volume and mass flow from in house to on-site calibrations of flow meters and the new measurement quantities pressure, temperature, relative humidity and direct current, direct voltage and DC resistance were accepted and is valid now since 6/16/2017. 

Mai 2017 : 20 Years TetraTec Instruments...

On the 1st of May 1997 we have started our business on our site in Steinenbronn as EP Instruments Messtechnik und Kalibrierung GmbH with 5 employees. 15 years ago in 2002 we fusioned with TetraTec Software & Engineering GmbH to TetraTec Instruments GmbH. And now 20 years after the beginning we became not only elder but also grew significantly regarding employees, turn over, area and supply range. 

Celebrate with us and visit our site in the year of the open house...

DAkkS-accredited calibration laboratory

June 2012 : Calibration lab instead DKD now DAkkS accredited :

The conversion of our ISO 17025 accreditation for our calibration laboratories by the new German Accreditation Office was achieved on 21 June 2012 by obtaining an accreditation certificate with the new registration number DK 17589-01-00. The previous registration number DKD-K-22301 is no longer valid after that date.

June 2012 : Member of technical committee of DKD for flow meas.

The former accreditation body DKD was merged into the German Accreditation Office (DAkkS) with effect from 1.1.2010. The DKD persists since then as a body for technical coordination between the calibration labs and the german Federal Institute for Technical Physics PTB. TetraTec is a member of the technical committee of DKD for flow measurement.

April 2012 : Martin Breckwoldt died young

Our longtime collegue Martin Breckwoldt, member of the calibration laboratory, died on Easter Sunday 2012 after a long, difficult illness at the age of just 38. We valued Martin as a very dedicated, lovable and able person and colleague. His untimely death has shocked us deeply and tears a big hole in our lives.

January 2010 : Extension of flow range up to 10.000 m3/h

Our high flow calibration chanel equipped with a turbine gas meter G6500 in nominal width of 400 mm and flow range of 500 to 10.000 m3/h went into operation. On the chanel flow meters with a pressure drop of up to 80 mbar can be calibrated with atmospheric air in suction operation.

November 2009 : Extension of our calibration laboratories

The extension of our calibration lab by another 100 m2 lab area was completed in June 2008. Since November 2009 we can offer calibrations for pure gases in our +/-0,1°C air-conditioned calibration rooms. With this step we have increased the number of available gases as well as the accuracy of our accuracies in the air flow ranges up to 1000 L/min.
