MULTICHANNEL ALARM/CONTROLLER FOR TOXIC GASES

TOX-ARRAY 2000 six channel controller uses chemically selective toxic, LEL, and O2 sensors. The Tox-Array no false alarm sensors developed by Mil-Ram do not react with air, have no zero drift, are not sensitive to changes in temperature, humidity, or pressure, and stay awake when gas is absent. Response time is less than 30 seconds to 90% of reading, and recovery to 90% is less than 15 seconds -- even if exposed to high gas levels. The chemically selective sensors have over four years no maintenance life for each factory charge. D.DAS can link 256 Controllers with a twisted pair of wires to monitor up to 1536 points with Windows-based real time data acquisition, TWA, STEL, PEL, Graphs, Curves.
