Nu hamnar vi över 410 ppm. I maj 2013 uppmättes för första gången dygnsvärden på över 400 ppm (miljondelar). Tillfället före det var för cirka tre miljoner år CO2-mätare, koldioxidinstrument från Swema. 16 § Luftkvalité anger att på arbetsplatser ska en koldioxidhalt under 1000 ppm (miljondelar) eftersträvas. Kalibrergasflaska (engångscylinder) för test eller kalibrering av gaslarm. Innehåll: 500 ppm CO2 (koldioxid) i luft; Mängd: 110 L. OBS! Levereras endast inom För bästa välbefinnande bör mindre än 750 ppm eftersträvas.

"We're in a new era," Ralph Keeling, director of the Scripps Institution's CO2 Program told Yale Environment 360 at the time we passed this milestone. Overview. The Quantek Model ZR1000 is a trace oxygen analyzer used for the measurement of trace oxygen in all types of inert environments.
