Professional interpretation of results — not just numbers

Always in line with the valid certificate and its annex

Accredited laboratory scope (ISO/IEC 17025)

Physico-chemical analyses and sampling in the fields of air, emission measurements, microclimatic conditions, noise, artificial lighting and vibration.

Emissions from stationary sources

Sampling, determination of emission components, TOC/VOC, particulates, NOx, CO, SO₂, O₂ and related parameters.

Workplace and indoor air

Dust, organic substances, chemicals, aerosols, fibres and operational exposure.

Microclimate

Temperature, pressure, humidity and air velocity in the workplace environment.
