Measurements

Air quality monitoring is carried out at the local and national level in order to estimate air quality and propose measures to reduce and prevent air pollution. These tasks are performed by testing laboratories authorized by the competent Ministry.

EKONERG Laboratory for air quality has many years of experience in measurements and is accredited according to the HRN EN ISO / IEC17025:2007 by the Croatian Accreditation Agency in the area described in the annex to the accreditation certificate number 1194.

In the field of air quality measurement, the laboratory performs the following tests:
