THE PRIMARY METROLOGY LABORATORY FOR NON-ELECTRICAL MEASURES, THE ML-03

 
The Laboratory has the authority of the Ministry of Defence and is accredited by the Accreditiation Board of Serbia according to ISO/IEC 17025/2006 standard for the calibration of standards and measuring equipment in:
 
-       pressure,
-       temperature,
-       relative humidity
-       acceleration of vibration
-       sound pressure and
-       length.
 
ML-03 is capable of callibration of excellent standards and measuring equipment such as:
micrometers, sliding standards, (echo) sounders, weights, scales with nonautomatic operation, scales with automatic and semi-automatic operation, accelerometers, vibrometers, manometers, barometers, barografs, altimeter, thermometer, thermograph, thermohygrografs, thermohygrobarografs, calibration furnaces, termostated bathrooms, air chambers, hygrometers, hygrografs, measuring microphones, measuring the level of noise and so on. (Scope of accreditation).
