The SST Model GT811 Toxic Gas NOVA-Sensor® is a completely self-contained device that measures and displays the concentration of gas accumulated in a protected area, performs local control functions, and optionally transmits this information to a central control point. The SST sensors use an electrochemical fuel cell with a patented diffusion barrier. Located inside a stainless steel flameproof housing, the sensing element is exposed to the detected gas through a suitable filter. The Model GT811 is suitable for the most demanding applications. A large body mass insures excellent vibrational characteristics when used for offshore use. Corrosion resistant materials permits uses in most environments. Available for the following gases: Hydrogen Sulfide, Sulfur Dioxide, Carbon Monoxide, Ammonia, and Chlorine.
