Calibration is confidence.
Precise measurement is the backbone of every drivetrain test. Regular calibration ensures that torque sensors, measurement equipment, and test benches, deliver accurate and traceable results that meet international standards.
It protects the validity of your data, avoids costly repeat tests, and gives your engineering team confidence in every result:
- Ensures accurate torque
- Supports ISO/IEC 17025 and internal compliance audits
- Detects sensor drift before it becomes a risk
- Secures repeatability and comparability across tests
- Minimizes test bench downtime and measurement uncertainty
Calibration targets.
Clearly defined.
At ATESTEO North America, we calibrate torque sensors from all brands. Quickly, reliably, and with full technical documentation. Our services cover individual sensors and entire measuring chains.
All calibrations are traceable, ISO-compliant and performed in our accredited lab in East Lansing. Every calibration is completed with a fast turnaround to minimize downtime and keep your testing on schedule.
From sensors to systems.
Measure with Accuracy
- Calibrations traceable to German Metrology Institute standards, compliant with ISO/EIC 17025
- Expanded measurement uncertainty as low as 0.02%, ensuring repeatable, reliable results
- Measurement ranges from 5 N·m to 10 kN·m via multiple reference sensors, covering large range of use cases
- Comprehensive performance metrics comparable and superior to other industry standards
- Results are carefully reviewed by experts and are cross-referenced with the sensor’s calibration history and manufacturer specifications

Note: While factory calibration is based on DIN51309 calculations, it’s not accredited and therefore does not serve as a proof of metrological traceability as DIN 51309 & VDI/VDE 2646 do.
