Indoor Air Quality-IAQ is a comprehensive concept involving various indoor gases and different kinds of low concentration pollutants. To detect and indicate IAQ level has becoming more and more important for the sake of establishing and maintaining healthy working and living environment.

F2000TSM-VOC series is specially designed to detect IAQ level in working and living environment and to further transmit the detected IAQ levels with corresponding analog output or to control a ventilator by one on/off output as pre-set IAQ level.

Its internal mixed gas sensor (normally called VOC sensor) is very sensitive to VOC concentration in the air (VOC i.e. Volatility Organic Compound, such as timber dope and toluene emitted by building materials), and other air pollutants such as cigarette smoke, ammonia and H2S. It also has high sensitivity to CO, alcohol, natural gas and odorous smells from human bodies. Compared with other single air sensor, Tongdy F2000TSM-VOC series is more suitable for IAQ detection in a long run.

F2000TSM-VOC series can also be used as a controller in application of ventilation and air conditioning systems to improve indoor air quality and to achieve the best energy saving.

Features:

uWall mounting, real time detect IAQ level

uWith Japanese semiconductor mix gas sensor inside. 5~7 years lifetime.

uThe sensor is sensitive to contaminative gases and various kinds of odorous gases within the room (smoke, CO, alcohol, human odor, material odor).

uTwo types available: indicator and controller

uIndicator is special design with six indicator lights to indicate six different IAQ levels.

uOne on/off output for the IAQ controller. When IAQ concentration is higher than the set point , the relay turns on to control a fan or another ventilator.

uFour setting CO level ranges selectable to control the relay output via a set of jumpers.

uRS-485 communication interface is another optional for both Indicator and transmitter types. 15KV antistatic protection, independent address setting.
