National Laboratory of Electrochemistry

DFM is the national laboratory for electrochemistry and one of the best laboratories in the world. Our two main focus areas are pH and conductivity, where we both perform accredited calibrations and produce certified reference materials.

We work constant to develop new services that are in demand by Danish companies but also to improve existing services. Most recently, we have added the area of coulometry to our list of competencies.

If you have questions, are looking for guidance or can not find what you are looking for on our website then contact us.
