Calibration and repair of your measuring instruments



‘MeterCare’ is the collective term for the timely calibration and repair of your measuring instruments. MeterCare from KWx takes care of calibration and takes the monitoring of the set calibration interval out of your hands. With MeterCare-Extra you will also get support in supplied software and user questions.

Brand-independent calibration of measuring instruments

If technical data is available, we can calibrate any reputable brand of measuring instrument. KWx has various calibration procedures available, including with ABB, Amprobe, BBC, Chauvin Arnoux, Extech, Gossen Metrawatt, Hioki, Fluke, Flir, Norma, Megger, Nieaf Smitt and Metrel. For instruments that fall outside our lab’s expertise, we collaborate with various external calibration laboratories.

Calibration according to standard EN ISO/IEC 17025:2017

Our calibration and repair laboratory is accredited by the RvA (Raad voor Accreditatie) according to the EN ISO/IEC 17025:2017 norm. You will never again have to carry out an audit yourself to check whether the calibration procedure is in order. A standard procedure has been developed for each type of test and measuring instrument, and we can also develop customer-specific procedures on request. Naturally, we carry out any repairs with original factory parts. We also provide a six-month warranty on replaced parts. If desired, the instrument can be provided with the latest product upgrades and NEN 3140 testing.

Which instruments do we calibrate?

We calibrate various test and measuring instruments, including:

No surprises: fixed rates

With MeterCare, you can be sure of fixed and known rates in advance. Should it turn out during the calibration of the measuring instruments that the instrument is not good, you will receive an obligation-free cost estimate in advance.

Calibration interval

MeterCare can determine the stability of the device after several calibrations. It is very important to monitor the calibration interval and change it if necessary, and MeterCare provides free advice about the calibration interval. Of course, you decide which interval is used. If, during calibration, it appears the instrument no longer meets the set specifications, we can adjust and recalibrate it after your approval, often using confidential factory data. You will then receive a certificate with the measurement results before and after the adjustment(s) being carried out.

Calibration call from MeterCare

To take the care of your measuring equipment off your hands, we include all measuring instruments from MeterCare in our database. In this database, all essential data of your measuring instruments are monitored. You will receive a call to have the instrument calibrated one month before the expiry of the agreed term. This service is free of charge!

Fixed lead times: A deal is a deal

Of course, you want a short lead time. With MeterCare, you can be sure of this: from the date of receipt, we will return your instrument(s) calibrated within five working days. However, you will need to make an appointment for this in advance. But if we exceed five days, then for each extra working day, we deduct 5% from the calibration price.

MeterCare Express

KWx reserves several hours per week for the so-called express calibration of measuring instruments. The turnaround time for express calibration is two working days. Please contact us about the conditions and rates.


Calibrations of measuring instruments are performed in our calibration lab MeterCare. If required, KWx will arrange for a parcel service or courier to pick up your measuring instruments. Ask us about the possibilities. Calibrated instruments are packaged by KWx and returned with a parcel service as standard.

Easily request a calibration report

If you have measuring instruments calibrated with us, you will have access to the calibration portal. Here you can log in and easily request calibration reports. This is done by scanning the QR code on the calibration sticker of your measuring instrument.
