Si Meccos iTr CO2 EV Monitor Gas Transmitter Universal Gas Alarm System 2001
Product Description
The Si Meccos iTr CO2 EV Monitor is a stand-alone CO2 gas transmitter and alarm system for continuous room-air monitoring. It is designed for laboratories, boiler rooms, storage areas, basements, conference rooms, theaters, restaurants, and other occupied spaces where carbon dioxide accumulation or gas leakage requires supervision.
The transmitter uses infrared spectrometry at a wavelength of 4.3 µm and provides local visual and audible alarms. Three integrated relay contacts support alarm, warning, and fault signaling, while the 4–20 mA analog output enables connection to external monitoring or building-management systems.
