GG-VL2-NH3 CTI Gas Sensor Vent Line Catalytic-bead Ammonia 0-1% 4/20 mA Output includes Mounting Kit

The GG Vent Line 2 utilizes a rugged ammonia-selective catalytic bead sensor technology for fast leak detection and long life. The standard 0-1% NH3 detection range of the GG-VL2-NH3 provides real-time continuous monitoring of ammonia concentrations in your high-pressure relief vent header.

Key Features:

• New ammonia-selective cat-bead sensor technology prevents false alarms
• Continuous monitoring of refrigeration system relief valves
• Rugged, long life, and low power catalytic-bead sensor
• Designed for harsh environments (-40°F to +140°F)
• Sensor and preamp in one assembly
• 0-1% NH3 (0-10,000ppm) detection range
• Ability to detect “weeping valves” to prevent refrigerant loss over time
• Sensor housing allows for easy sensor replacement and calibration
• 316 stainless steel 18 gauge enclosure
• Industry standard 24VDC, linear 4/20 mA output
