Honeywell Analytics Carbon Monoxide Transmitter TP1-M

Honeywell Analytics Carbon Monoxide Transmitter


The Honeywell Analytics Model TP1-M Carbon Monoxide Sensor features a two-wire, 4-20 mA output signal and two alarm outputs. This CO sensor is the first available zero-maintenance CO gas monitor with an electrochemical sensor. The carbon dioxide detection unit is ideal for building automation systems, BAS, and HVAC applications. It has a low initial cost and installs quickly and easily into a standard single-gang outlet box. It has a two to three-year operational life and never needs calibration. The Carbon Monoxide monitoring sensor is designed to be used as part of a control system. When properly installed and maintained, the sensor helps to prevent the formation of a hazardous environment. For more information on the proper application and use of this product please read "Environmental Safety Devices" in our technical reference section.
