Versions with an LCD display
DEGA NSx-EL III LCD with an electrochemical sensor
They operate on the principle of change of electrical parameters on the electrodes stored in electrolyte, due to
oxidation/reduction reactions of the detected gas on it's surface. These sensors have good selectivity and the ability to detect
very low concentrations of toxic gases.
DEGA NSx-CL III LCD 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 LCD 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
