DEGA NSx-CL III with a catalytic sensor (Pelistor)
They operate on the principle of catalytic combustion - gas concentration is measured based on the amount of heat released
in a controlled combustion reaction. The reaction is supported by a suitable temperature and the pressence of a catalyst.
These sensors can be used to detect a broad range of flammable gases. The sensors are characterized by fast response,a long
lifetime and high stability. A minimum of 10% of Oxygen in the air is required for it's proper function.
DEGA NSx-IL III with an infrared sensor (NDIR)
Top quality scanning method. They operate on the principle of infrared spectroscopy. The sensors have excellent selecivity in
organic matter, do not require any oxygen in the atmoshpere and are resistant to catalyst poisons (sulfur and silicon
compounds) which cause a change of sensitivity of catalytic sensors. The sensors are characterized by high stability and a long
lifetime.
DEGA NSx-SL III with a semiconductor sensor
Cheapest method of scanning. They operate on the principle of changes in electrical conductivity of semiconductors by
changing the concentration of the detected gas. Their advatage is a long lifetime in a clean environment and a wide range of
different types of gases and vapors. Their disadvatage is their low selectivity - the sensor largly responds to other gases for
which it is not calibrated.
