H.P.F.M. B.V. High Pressure - Force Metrology, is operating in the calibration quantities pressure, (vacuum) force (mass) & torque. Special projects are being executed with the use of the equipment now for sale, due to that these projects are finished, and also that I only will proceed in the pressure calibrations till 16250 BarG. But soon this unique metrology-calibration equipment, based on the controlled clearance piston gauge technology, to be called an international primary pressure standard, will be sold too.
