GG-NH3-2% CTI Gas Sensor Ammonia 0-2% (0-20000 Ppm) 4/20 mA Output Ammonia Selective Catalytic Bead Sensor

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.

Key Features:

• Ammonia selective catalytic bead sensor technology
• Useful for activation of electrical shunt-trip or E-stop up to 20,000 ppm
• Low cost compared to infrared type ammonia sensors
• Industry standard linear 4/20 mA output
• Absolutely no zero drift compared to other catalytic bead type sensors
• Sensing element designed for long life in harsh industrial environments
• Designed to perform in temperatures of -40°F to +150°F
• Accurately monitor explosive NH3 levels for emergency response situations
• Real-time continuous monitoring
• 2-year warranty, including replacement sensor element
