Our measurement instruments meet both national and international standards. Their technical parameters are confirmed by type approvals issued by the Central Office of Measures in Poland as well as certificates issued by other institutions.

ATTENTION !!! Sound level meters made by SONOPAN aren’t either "decibel meters" or "sonometers", but they are the measurement instruments which meet the standards for sound level meters. The instruments which are sold on the market and are referred to as “decibel meters” or “sonometers” don’t usually conform to the requirements for sound level meters.
