NOVUS' Metrology Laboratory updated its scope


Proven quality

Following the audit conducted in October, the accreditation of the NOVUS' Metrology Laboratory with the Brazilian Calibration Network was renewed, and its scope was updated. The scope of calibration, for services performed in the laboratory and for services performed on the customer's facilities, is fully described below.

 

Since 2009, NOVUS' Metrology Laboratory has been accredited by CGCRE (INMETRO's General Accreditation Coordination) and carries out calibrations of its own and third-party equipment. Thus, the brand can deliver already calibrated instruments, guaranteeing the quality and high performance of controllers, sensors, data loggers, and other products.
