On-site calibration

We calibrate your test equipment and measuring points on your premises with professional competence and high precision equipment. More than 300 trained technicians and engineers are on duty for you throughout Germany.   

We from Testo Industrial Services come directly to you on site and guarantee here too - more service and more safety with our full-service performance. 

  • You cannot do without your test equipment? 
  • Do you need maximum availability of your test equipment? 
  • Do you need short lead times? 

We calibrate your test equipment directly on site at your plants, climatic chambers and test benches or in one of our mobile and air-conditioned calibration laboratories. With our wide range of calibrations, we cover all your requirements. From the calibration of standard-length measuring devices, to the calibration of special electrical measuring devices, to GMP compliant calibration in the pharmaceutical environment. Our comprehensive range of services enables us to perform traceable ISO/factory calibrations as well as accredited calibrations according to DIN EN ISO/IEC 17025:2018 at your site.

Calibration of test benches & stationary equipment

For safe processes and procedures, you need measurement technology whose accuracy and reliability you can trust. Regular calibration is a prerequisite for the quality of your products and systems. We at Testo Industrial Services calibrate all quality relevant measuring points directly at your plants.

  • Calibration of stationary equipment in a GxP regulated environment 
  • Calibration of dynamometers, engine test benches, transmission test benches, individually developed test benches as well as environmental simulation chambers
  • Calibration of all quality-relevant measuring points on your stationary systems, e.g. test bench for e-drives 
  • Calibration of your process measurement technology on your systems, e.g. in the food and beverage industry

Logger for environmental conditions

We take over the calibration of your humidity and temperature loggers directly at your site and thus ensure some advantages for you.  

  • No recording gaps and no downtime 
  • No transport costs 
  • Low administrative effort

Performance testing of temperature and climatic chambers

In addition to your loggers and test benches, we can calibrate everything from small temperature test chambers to large climate chambers for environmental testing (e.g. from the automotive sector) with the help of our trained technicians and engineers directly at your site. 

  • Calibration of individual measuring points
  • Performance testing of the temperature/climate chambers 
  • Verification of additional properties (e.g. Inhomogeneity, stability of the characterization of the cabinet and possible effects on the test material in the cabinet)
