Calibration procedure in our laboratory

Save valuable time by using our pick-up and delivery service. By using our rental boxes, you can rest assured that your measuring tools will be transported quickly and reliably. Once your measuring tools arrive at our calibration laboratory, they are first prepared for the calibration and brought to the right temperature. During the calibration, the measuring tools are checked using specialised processes and, upon request, calibrated in accordance with VDI and DAkkS. The outcomes and potential deviations from the test standards are evaluated and documented in a calibration certificate. After the calibration, we send the item back to you safely, together with the calibration certificate. 

Here you will find the right calibration service for you.

At the Hoffmann Group, new items can be ordered already calibrated. In this case, the new item will be delivered with a calibration certificate and, if you wish, registration for trendic® 3.5 measuring tool management. In addition to our new-item calibration and recalibration services in our calibration laboratory, we also provide an on-site calibration service for measuring devices, such as height gauges, measuring microscopes and torque wrenches.

What are the differences between factory calibration and DAkkS calibration?

trendic® 3.5 – the new measuring tool management and calibration software – provides you with innovative possibilities. Through the use of a specially developed unique ID, measuring tools become “talking measuring tools” within the context of Industry 4.0. By scanning the code on a tool, trendic® 3.5 provides you with all the information about that particular measuring tool, which helps you to manage and observe relevant dates for the calibration work. trendic® 3.5 considerably reduces time and costs when it comes to measuring tool management.

FAQ

How often should measuring tools be calibrated? 

It is usually up to the Quality Management department in a company to determine how often a measuring tool should be calibrated. As well as using cycles or frequency of use to determine the time of recalibration, it is advisable to have measuring tools calibrated after incidents, e.g. if they have been dropped. 

When is DAkkS calibration necessary?

DAkkS calibration is necessary when the result of the calibration must be traceable to the national standard and be recognised on an international level. DAkkS calibration is also recognised in court. Furthermore, since September 2018, IATF 16949 prescribes DAkkS calibration for manufacturing activities in the automotive sector.
