GG-NH3-2%-ST CTI Gas Sensor Ammonia 0-2% (0-20000 Ppm) 4/20 mA Output Ammonia Selective Catalytic Bead Sensor
High Range Ammonia sensor designed for catastrophic leak detection and electrical shutdown in compressor rooms, with the added durability of a stainless steel enclosure.
The GG-NH3-2% is designed to detect and monitor potentially explosive levels of ammonia vapors in the event of a catastrophic failure. Codes specify an electrical shunt-trip of the mechanical room at a level not higher than 25% LEL to remove potential ignition sources in the event of a serious ammonia leak. The GG-NH3-2% allows for an earlier trip level of 12.5% LEL.
