Terminology

The marking system for detector DEGA NSx-yL III LCD:
Gas detector DEGA
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
oxida�on/reduc�on reac�ons of the detected gas on it's surface. These sensors have good selec�vity and the ability to detect
very low concentra�ons of toxic gases.
DEGA NSx-CL III LCD with a cataly�c sensor (Pelistor)
They operate on the principle of cataly�c combus�on - gas concentra�on is measured based on the amount of heat released
in a controlled combus�on reac�on. The reac�on 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
life�me and high stability. A minimum of 10 % of Oxygen in the air is required for it's proper func�on.
