Lefoo Electrochemical CO Sensor LFG101

LEFOO LFG101 wall-mounted carbon monoxide transmitter uses electrochemical principle to detect carbon monoxide in the air, with good selectivity and stability. Three output modes of current, voltage and RS485 are optional. It uses wide voltage power supply and power supply anti-reverse polarity protection. It is suitable for carbon monoxide gas monitoring in indoor air quality detection, air conditioners, air purifiers, underground parking lots and other occasions.

Features

* High Linearity Sensor Provides Accurate and Reliable Stability

* Good repeatability, service life is more than 5 years

* Optional output signal, power reverse connection protection

* Double-layer waterproof membrane design effectively prevents water vapor from entering, and the sensing element is non-toxic

Applications of Electrochemical CO Sensor LFG101

An array of factors can impact the quality of indoor air, and it's imperative to monitor for contaminants, particles and gas. Carbon monoxide, for example, is known as a silent killer, with exposure sending many people to the emergency room every year.

It is a combination of a mature electrochemical detection principle and sophisticated circuit design. In facility management, there are numerous important elements that supervisors need to keep track of in order to maintain operations and ensure a safe and healthy environment for workers. Particularly in industrial settings, not the least of these considerations is air quality.
