This series transmitters are designed for monitoring & controlling indoor air quality (CO2 concentration)

CO2DWNL is for wall mount and CO2DDL is for duct mount

CO2DDL uses a patented probe structure for excellent sampling performance

Good performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation

Over voltage and reverse polarity protection, high reliability and anti-interference capability

All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring (for CO2DWNL)

Dual outputs 0~10V and 4~20mA supply flexible application

10 years sensor life without maintenance
