Calibration of dimensional measurands
In our dimensional calibration laboratory we calibrate your length measuring equipment with the highest precision. These include indicating test equipments, measuring standards, test equipments and angles.
In order to ensure the measurement results, our premises are air-conditioned to a temperature of 20 °C ± 1 K. This ensures standard-compliant and reliable calibration in our dimensional laboratories. For the calibration of test equipment blocks, even rooms with a temperature range of 20 °C ± 0.5 K are available.
Characterized by a high number of calibrations per day, many processes are optimized and automated in order to relieve the time-consuming manual calibration process. Our laboratory has a fully automated measuring robot, which calibrates calipers for you within a very short time, with very low measurement uncertainties. In addition to the normative calibration scope such as external, internal, depth and step measurements, the light gap tests and ease of movement tests are also carried out fully automatically with the calibration robot, thus relieving the manual calibration process.
For the calibration of thread rings and thread mandrels, several thread scanners are used in order to be able to make statements on the pitch and flank angle in addition to the usual pitch diameter. For the area of dial test equipments, several fully automatic dial test equipment test stations are in use, which determine process-reliable and reproducible measured values via a camera system without operator influence. Furthermore, we are optimally equipped for the calibration and measurement of your individual workpieces, test equipments, assemblies and much more.
Furthermore, our long-standing exclusive partnership with the manufacturer Keyence distinguishes us. This gives you the opportunity to carry out accredited calibrations of optical measuring instruments directly at your premises with minimum downtime.

In the industrial environment, a tightly fitting screw connection is unavoidable. Many thread types and diameters are used. In addition to the simple pitch diameter, which is often tolerated by standards, other parameters such as the pitch, the flank angle, but also the core or outer diameter can be decisive for a tight and secure threaded connection.
We at Testo Industrial Services calibrate a large number of your thread ring test equipments or taper thread ring test equipments with our thread scanner. High-precision contour scanning of the entire thread profile enables process-relevant statements to be made.
