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 alarmsContinuous monitoring of refrigeration system relief valvesRugged, long life, and low power catalytic-bead sensorDesigned for harsh environments (-40°F to +140°F)Sensor and preamp in one assembly0-1% NH3 (0-10,000ppm) detection rangeAbility to detect “weeping valves” to prevent refrigerant loss over timeSensor housing allows for easy sensor replacement and calibration316 stainless steel 18 gauge enclosureIndustry standard 24VDC, linear 4/20 mA output
