Halk has been fully accredited by the Dutch Measurement Institute (NMI), which has been appointed by the Dutch Ministry of Economic Affairs, Agriculture and Innovation, for the inspection of non-automatic weighing instruments (NAWI). We are also authorized and equipped to carry out these inspections on site. This makes us the ideal partner for industrial bulk and process companies who strive to achieve high quality. Many ISO-9001 certified companies, in particular, make use of our inspection and calibration services each year.
