Nitrogen Dioxide (NO2) Gas Detector

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.

The Nitrogen Dioxide (NO2) Detectors have a built-in electrochemical Nitrogen Dioxide (NO2) sensor.

Numbers of Nitrogen Dioxide (NO2) Detectors per square meter is different depending on local regulations, country regulations and applications.
Recommended (role of thumb) is one Nitrogen Dioxide (NO2) Detectors per 400 m2.

Mounting height for Nitrogen Dioxide (NO2) Detectors is 0.2 meter above floor.

Nitrogen Dioxide (NO2) gas detector RNO2-series available for
wall mounting, duct mounting and wall mounting with
3 meter cable and remote sensor.

Facts about Nitrogen Dioxide (NO2) gas and Nitrogen Dioxide (NO2) Gas Detectors

Nitrogen Dioxide or NO2 gas is reddish-brown in color with a sharp characteristic and with arctic odor is a protuberant air pollutant. This Nitrogen Dioxide (NO2) gas mostly found in industries where diesel is used as fuel. Exposure of this Nitrogen Dioxide (NO2)gas have harmful reactions over our body parts like eye, throat etc. More exposure of this Nitrogen Dioxide (NO2) Detectors can be the cause of death. So protection from this Nitrogen Dioxide (NO2) Detectors is very necessary and important. In this regard Nitrogen Dioxide (NO2) Detectors can help to a great extend to avoid the risk related to this injurious Nitrogen Dioxide (NO2) Detectors.

Nitrogen Dioxide (NO2) Detectors can detect the gas quantity and warn when the amount of harmful Nitrogen Dioxide (NO2) Detectors touches a harmful level. This type of Nitrogen Dioxide (NO2) Detectors are used in different applications liketruck and bus garages, road tunnels, underground garages, engine repairing shops, engine test benches, tunnels, shelters, loading bays with diesel-engine vehicles, and in other places where fuel is diesel such as any industry. Nitrogen Dioxide (NO2)is produced when hydrocarbons burn. Arrangement of these Nitrogen Dioxide (NO2) is a good investment to avoid health problems and to avoid different expenditures. For example if a bus garage have this detector, then the workers get warning if the harmful Nitrogen Dioxide (NO2)gas level increase and can do their job properly.

To make sure that the arrangement of ventilation is properly done Nitrogen Dioxide (NO2) Detectors are used. Fresh air must be present as per requirement quantity for a healthy environment. When the level of Nitrogen Dioxide (NO2) becomes high, the fan of the detector starts spontaneously and stops again when the level of Nitrogen Dioxide (NO2) has down to the required level. These Nitrogen Dioxide (NO2) Detectors have a built-in sensor to detect this unhealthy Nitrogen Dioxide (NO2)gas. When Nitrogen Dioxide (NO2)gas level is high, you can also listen a warning horn if installed. This horn indicates that your environment needs fresh air to reduce this unhealthy Nitrogen Dioxide (NO2)gas.

Nitrogen Dioxide (NO2) Detectors can measure 0-1 ppm , 0-5 ppm, 0-20 ppm and 0-100 ppm These Nitrogen Dioxide (NO2) Detectors not only try to minimize the harmful gas level but also warn you about the situation. So, you can aware and arrange proper ventilation in your work area.

These Nitrogen Dioxide (NO2) Detectors will help you to manage and work in a healthy environment. Many diseases spread due to Nitrogen Dioxide (NO2) gas. If you are aware about the advantages of Nitrogen Dioxide (NO2) gas, you will escape from mishaps occur due to this harmful Nitrogen Dioxide (NO2) gas in air. Industries can use these Nitrogen Dioxide (NO2) Detectors Detectors to provide a healthy environment and can avoid risks that may occur due to Nitrogen Dioxide (NO2) gas.
