Sensoren voor NO2 | Samen meten aan luchtkwaliteit

+

De sensordata voor NO2 die het RIVM momenteel op het Samen Meten Dataportaal toont, is gemeten met de NO2B43F. Het RIVM past een kalibratieprocedure toe om te komen van het sensorsignaal (elektrische spanning) tot de getoonde NO2 concentratie. De sensor heeft als output elektrische spanningssignalen. Deze signalen zeggen iets over de NO2concentratie in de buitenlucht. Hoe hoger …

Stikstofdioxide (NO2) | Samen meten aan luchtkwaliteit

+

Stikstofdioxide (NO2) Inleiding. Stikstofdioxide (NO2) is een gas dat in Nederland voor een groot gedeelte door het autoverkeer wordt geproduceerd. Het is daarom een belangrijke indicator voor de luchtverontreiniging door verkeer. Langs grote wegen komen hoge concentraties voor die over een afstand van enkele kilometers afnemen tot lage concentraties. Stikstofdioxide draagt bij aan smog ...

NOx emissions from diesel engines Clean carbon energy

+

Why are NOx gases harmful? A. Internal combustion engines can produce all three nitrogen oxides. Nitrous oxide (N 2 O), also known as ''laughing gas''. It is a serious greenhouse gas, and is defined as being 298 times as bad as CO 2 because of its radiative effect, and the time taken to break it down. Used as an anaesthetic and generally considered to be nontoxic. It does react with vitamin B12 ...
