Our History

For almost 30 years, since 1990, Kalibra has been the organisation for all your calibrations, validations, and inspections. We are also recognised by several international bodies.

Since 19 June 2009, we are part of ENGIE Netherlands. Regardless, we are the same Kalibra as before, with our familiar customer-oriented and personal approach.

Kalibra has the biggest range of services for all on-site calibration and validation.

We offer the following services:


Calibration is the comparison of a measured value using a measuring system with an actually measured value with a standard to determine the deviation.


Validation of critical facilities, spaces, instruments, and equipment provides insight into whether requirements are met, and therefore whether an object is suitable for the intended goal.


Metrological inspection involves testing whether a measuring instrument complies with metrological legislation. Kalibra is a formal inspection body. We carry out inspections as an independent institution. A metrological inspection guarantees objectivity and expertise.

Calibration of Measuring Instruments

Kalibra is an expert in the field of different types of calibrations. We can calibrate both individual measuring equipment as well as permanently installed measuring equipment in the production process.


Trained and experienced Kalibra employees are available on call for a either a short or longer period. Even a couple of days a year is possible.
