INSTRUMENT
CALIBRATION LABORATORY
THE ACTIVITIES
The metrology laboratory of P&P LMC boasts over twenty years of experience in calibration and certification services for mechanical, electromechanical, electronic, chemical and electro-medical measuring instruments.
The activities are carried out within a Quality Management System compliant with the standard UNI EN ISO 9001:2015 and with the requirements of the standard UNI CEI EN ISO/IEC 17025:2018as a guarantee of reliability, technical competence and process control.
Particular attention is paid to the impartiality of measurement results and to the control of internal processes, through a Quality System focused on the prevention of non-conformities and the continuous improvement of the service.
CALIBRATIONS WITH ACCREDIA CERTIFICATE
The laboratory is certified according to the ISO 9001:2015 standard and is accredited as LAT N. 00403, compliant with the UNI CEI EN ISO/IEC 17025:2018 standard, accredited for the following sectors:
- acceleration (accelerometers – vibrometers),
- length (displacement transducers),
- temperature (probes and thermometric chains),
- pressure (pressure gauges and pressure transducers) in liquid and gaseous media.
Accreditation offers a guarantee that certifies the technical competence of the laboratory to perform the calibrations listed in our accreditation table available on the ACCREDIA website:
