On-site calibration
We calibrate your test equipment and measuring points on your premises with professional competence and high precision equipment. More than 350 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.

Test benches and stationary systems

Accurate and reliable measurement technology is essential for safe processes and procedures. Regular calibration is a prerequisite for product and system quality.
We calibrate all quality-relevant measurement points directly on your systems.
- Calibration in GxP-regulated environments
- Calibration of performance and engine test benches, gearbox test rigs, custom-built systems, and environmental simulation chambers
- Calibration of all relevant measurement points on stationary systems
Loggers for environmental conditions

We calibrate your humidity and temperature loggers directly on site.
- No recording gaps or downtime
- No transportation costs
- Reduced administrative effort
Functionality testing of temperature and climate chambers

We perform performance testing and calibration of temperature and climate chambers directly on site, from small units to large environmental simulation chambers.
- Calibration of individual measurement points
- Performance testing
- Analysis of additional properties such as homogeneity and stability
On-site camera calibration

For precise measurement results, camera calibration is essential. Calibration under real operating conditions ensures long-term measurement accuracy in industrial image processing.
- Calibration of area and line cameras
- Distortion correction
- Measurement system analyses (MSA)
- Creation of customer-specific references such as checkerboard patterns
- Ensuring measurement accuracy
CQI and AMS Testing

Testing according to CQI and AMS ensures compliance of heat treatment and coating systems.
- Testing according to CQI 9, CQI 11, CQI 12, and AMS 2750
- System Accuracy Test (SAT)
- Temperature Uniformity Survey (TUS)
- Calibration of thermocouples and instruments
- Execution under real operating conditions
GMP-compliant calibration

To meet your metrological requirements in GxP-regulated environments, we provide over 4,500 references and measurement systems, covering almost all pharmaceutical-relevant parameters.
Our GxP Services team, with more than 250 engineers, technicians, and specialists across Germany, is fully familiar with all relevant standards and regulations. We support you with expertise, the right equipment, and personnel resources to handle peak workloads or provide long-term support for your calibration tasks.
Risk-based calibration managementScope of services of our measured quantities at a glance for your on-site calibration
