In the service center or comfortably at your location

When performing a service or repair, we will follow your specifications and requirements, offering solutions tailored to your specific needs. If required, our experienced service technicians will come to your place and work in accordance with established policies in on-site service. Alternatively you can send your device to our service center, where it will be expertly reviewed by our service team.


Regular maintenance increases the life of your instrument while meeting the ever-increasing demands of quality assurance. Depending on the working environment of your device, annual maintenance is recommended.

We offer a cost-effective maintenance check: in addition to preventive maintenance, your device is professionally cleaned, checked, adjusted and calibrated. On request, we also carry out a VDE examination according to DGUV. Of course, you will receive a detailed maintenance and calibration record for your documents, which documents the work carried out comprehensibly.

Optionally with service and maintenance contracts

To increase your comfort, we offer the conclusion of service and maintenance contracts. The maintenance contract ensures maximum safety for a complete, regular and preventive check of your measuring instruments, which ensures measurement accuracy and trouble-free operation in the long term. Thanks to regular maintenance, the units can be operated with optimum performance and deliver reliable results. You avoid downtime and unnecessary repair costs and your maintenance costs become a predictable size. By concluding a maintenance contract, you can be sure that your equipment will always meet the required standards, that maintenance intervals will not be exceeded, and that the annual commercial process will run smoothly and straightforwardly for your company.

Use the A.KRUESS know-how. Just give us a call; we’ll take care of everything.

Even the most reliable device may be broken once. Repair work is carried out quickly and professionally by our experienced service team. Like the maintenance, we offer our repair services as a service to you on site or in our service center.

Return your device | Return Form

You would like to send your A.KRUESS device to our service center for maintenance or repair? For the return we provide a PDF form, which you must fill in completely and attach to the return. The form contains your error or task descriptions as well as important safety information.

Many laboratories work with biological, infectious, radioactive or toxic substances. This can lead to residues on the devices. In order to protect our employees, we ask you to carry out a thorough cleaning, possibly decontamination and disinfection of the respective device before returning it.

Please note that our service team can repair or maintain your device only upon receipt of the completed return form. Shipments without this certificate cannot be processed for security reasons and will be returned to the sender at a charge.
