KEEPING YOUR HILTI TOOLS PRECISE AND ACCURATE

We offer a calibration service to test and readjust your Hilti measuring tools including:

• Laser distance measurers
• Laser levels
• Point & line lasers
• Concrete scanners

Our Hilti tools are all designed to be high precision instruments. But sometimes their accuracy can be affected by harsh conditions, such as inappropriate storage, temperature fluctuations or mishandling. Accuracy can also be affected over time by rigorous conditions of everyday use.

We therefore recommend that you calibrate your tools regularly, at least once a year.

In some cases you may need to calibrate your tools more often, so please check with your own Internal Quality Policy to see what you need to fit with your company’s internal audits.

We also recommend that you regularly field test your tools, particularly before critical measurement tasks and if your tools have been subjected to harsh conditions.

You can find more information about this in your tool’s Operating Instructions.

1. Verification of accuracy

We compare your tool’s accuracy with the accuracy defined by our “manufacturer’s specifications” in its user manual.

2. Adjustment, clean and service
If the tool doesn’t conform to its original specifications, we adjust the laser level or detector to make it accurate again. We also clean the tool and check that it’s working correctly before sending it back to you.

3. Documentation
We give you a written report, listing the measurements we’ve carried out for the ingoing and outgoing test values. We also include a Service Certificate confirming that the tool now complies with its original manufacturer’s specifications.

Pease note that Hilti’s verification procedure is not accredited under ISO 17025 or any other certification standard, which is specifically designed for calibration laboratories.

Please refer to your Internal Quality Policy to check whether calibration according to a standard such as ISO 17025 is required.

If you have any questions, please just contact your local Hilti team.
