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, as they ensure that heat-treated components meet the required specifications. In addition, measurement section testing and measurement section calibration are indispensable measures to ensure the precision of temperature measurement systems.

TUS measurement (Temperature Uniformity Survey)

The TUS measurement 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:

✅ Sensor placement and measurement
✅ Detailed evaluation of temperature distribution
✅ Documentation according to current standards
✅ Advice on how to optimize your furnace processes

SAT measurement (System Accuracy Test)

The SAT test 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:

✅ Calibrated comparative measurements with highly precise reference sensors
✅ Analysis of measurement results and deviations
✅ Recommendation of corrective measures in case of deviations
✅ Documentation according to standard specifications

Measurement section check and measurement section calibration

For reliable temperature measurement, the proper functioning of the entire measuring section is crucial. The measuring section check ensures that the lines up to the measuring instruments are working correctly. The measuring section 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
