Carbon monoxide sensor CO

Features

TP1-M Carbon Monoxide Sensor/Transmitter features a two- wire, 4-20 mA output signal and two alarm outputs. It is the first available zero-maintenance CO gas monitor with an electrochemical sensor. The Model TP1-M has a low initial cost and installs quickly and easily into a standard single-gang outlet box. It has a three-year operational life and never needs calibration
