Laboratory for primary standards of basic electrical quantities, the ML 01


The laboratory is authorized by the Ministry of Defense to calibrate standards and benchmarks in the areas of:

-          AC and DC electric voltage,
-          AC and DC electrical current,
-          Electrical resistance
-          Electrical capacitance,
-          Electrical inductance and
-          Sharing ratio of DC and AC voltages.
ML-01 is capable of callibration of excellent standards and measuring equipment such as: Weston cells, calibrators of DC and AC voltage, AC/DC standards and termoconverters, multimeters, voltmeters, amperemeters, ommeters, bridges for inductance, capacitance and resistance, resistance of standards, capacitance and inductance, distortion meters, kilovoltmeters etc (scope of accreditation).
