GAS DETECTION SYSTEMS SDK-2
|
Purpose
Gas detection systems SDK-2 are wall mounted multichannel controller wich operate in conjunction with up to eight explosion proof pellistor detector BS-1 to detect the presence of flammable gases and vapours in air, digital indication at LCD of measuring meaning, sound and light alarm at the exceeding of fixed thresholds. |
