Accredited calibration lab for VOLUME, MASS FLOW, PRESSURE GAS and TEMPERATURE
Since 2017 Mega System Srl is also LAT calibration laboratory N°262T, accredited by ACCREDIA, the only national body authorized by the state to carry out accreditation activities.
Following the positive evaluation obtained in July 2017, ACCREDIA issued the Accreditation Certificate to our Center confirming the adequacy of the Calibration Laboratory to issue LAT certificates for Volume and Volume capacity of gas, in October 2018 for Pressure and in July 2022 for Temperature.
What guarantees the ACCREDIA certification?
The ACCREDIA certification guarantees that our laboratory is adequated to UNI CEI EN ISO / IEC 17025 standard and in compliance with the requirements of other mandatory or voluntary standards.
An accredited calibration center has:
- a company management system in quality assurance
- the technical competence to execute accredited calibration of sampling instruments and gas and volume measurement of ambient gases

(*) The measurements uncertainty is expressed at the trust level of 95%
(**) The expanded measurement uncertainty value is obtained by summing the values of the two components in quadrature with the formula (2√u12 + u22) and is expressed with 2 significant digits, where Uris indicates the standard uncertainty due to the resolution of the instrument in calibration expressed in °C
