Macurco TX-12-AM Ammonia NH3 is a line voltage, dual relay Ammonia (AM) detector and automatic ventilation controller. The TX-12-AM uses a microcomputer controlled, electronic system to measure the concentration of Ammonia, actuate relays and provide a 4-20mA output. The TX-12-AM has a field replaceable, electrochemical sensor (expected life of 2+ years) and optional gas test and calibration kits. The TX-12-AM is a low level meter capable of displaying from 0-100 ppm of Ammonia.
The TX-12-AM provides Ammonia detection and automatic exhaust fan control for industrial refrigeration, warehouses, hockey rinks or other commercial applications. Ammonia or NH3 is a colorless gas with a pungent, suffocating odor. Note: Shipped as a liquefied compressed gas – easily liquefied under pressure. The TX-12-AM is designed to meet the NIOSH and OSHA standards for Ammonia exposure limits. TX-12-AM can be used stand alone, with the Macurco DVP-120 Detection and Ventilation Control Panel, other fire/security panels or building automation systems.
