LF-TCO Carbon Monoxide Transmitter

According to many building HVAC regulations, it is necessary to control the ventilation of closed parking lots and vehicle maintenance and inspection workshops. It is recommended to adopt on-demand controlled ventilation (DCV) to provide sufficient fresh air according to the CO concentration. This series of products are specially designed for these applications and can effectively control the safety and energy saving of ventilation.

Using electrochemical sensors to provide accurate, reliable and sensitive long-term monitoring.

The sensor has a lifespan of more than 5 years, long-term stable performance, low drift, and can be verified after 12 months or later as required.

Applying digital technology, a variety of output modes are available, overvoltage and reverse connection protection, high reliability, and strong anti-interference ability.

Different shells adapt to different installation methods and environmental requirements. CMWL wall-mounted type has a higher protection level, and CMWNL is suitable for general indoor installation.

Features

Real-time detection of the concentration of carbon monoxide in the underground garage environment.
Multiple fire compartment concentration values are displayed and monitored centrally, and the concentration values are displayed in real time.
The alarm value can be set freely, and the exhaust system can be automatically linked when the concentration value exceeds.
High linearity and high stability
Good repeatability and long service life
High-precision electrochemical sensor, no need for calibration and replacement on site
Double-layer waterproof membrane design effectively prevents water vapor from entering, and the sensing element is non-toxic
