npi celebrates 35 years!


The founder of npi, Hans Reiner Polder, developed during his diploma thesis (TU Munich, 1984, made at the Max-Planck-Institute for Psychiatry) a new compensating method for intracellular measurement amplifiers, which was used together with control theory approaches to increase the measuring range.

35 year ago, this was the basis of a new generation of amplifiers and the beginning of npi electronic.
