Nitrogen Dioxide (NO2) Detectors are used in applications such as bus- and truck garages, under ground garages, road tunnels, engine repair shops, tunnels, engine test benches, shelters, mountain cavities, loading bays with diesel engined vehicles.
Nitrogen Dioxide (NO2) Detectors are used to warn when the quantity of harmful gases reaches an unhealthy level.
Nitrogen Dioxide (NO2) Detectors are used to ensure that the management of ventilation is done the best and most profitable way, ie. according to fresh air requirements.
When the concentration of Nitrogen Dioxide (NO2) becomes too high, the fans starts automatically and stops again when the Nitrogen Dioxide (NO2) concentration has down to the predetermined level.
