Temperature uniformity testing (TUS) and system accuracy testing (SAT) are essential procedures to ensure high quality and reproducibility of thermal processes. These measurements are particularly important in the aerospace (AMS2750), automotive (CQI-9) and metal processing industries (NORSOK M-650), as they ensure that heat-treated components meet the required specifications. In addition, measurement point testing and measurement point calibration are indispensable measures to ensure the precision of temperature measurement systems.

TUS (Temperature Uniformity Survey)

The TUS is used to check the temperature uniformity inside the process chamber of an industrial furnace. This is done by placing several temperature measurement points in the working area of the furnace and recording them over a specific period of time. This is particularly important for industries with strict quality standards, such as the aerospace (Nadcap standards) or automotive industries.

Our services:

✅ Use of high-precision and calibrated recording devices from YOKOGAWA and EUROTHERM
✅ Positioning the sensors and carrying out the measurements
✅ Detailed evaluation of the temperature distribution
✅ Documentation according to current standard specifications
✅ Advice on optimising your furnace processes

SAT (System Accuracy Test)

The SAT checks the accuracy of the entire measuring system by comparing the furnace’s control thermocouple with an external reference thermocouple. This test ensures that the measured temperatures correspond to the actual values and are not distorted by sensor aging or calibration errors.

Our services:

✅ Use of high-precision and calibrated measuring devices from BEAMEX
✅ Comparison measurements with high-precision and calibrated reference sensors
✅ Analysing the measurement results and deviations
✅ Recommendation of corrective measures in the event of deviations
✅ Documentation in accordance with standard specifications

Measurement point check and measurement point calibration

For reliable temperature measurement, the proper functioning of the entire measuring section is crucial. The measuring point check ensures that the lines up to the measuring instruments are working correctly. The measuring point calibration shows deviations and offers the possibility to compensate for deviations.

Our services:

✅ Checking the entire measuring section for function and accuracy
✅ Identifying and correcting measurement errors
✅ Calibration of the measuring section
✅ Documentation of the measurement results for verification purposes
