Wholesale gas detector for VOC
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-L 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
u Wall mounting, real time detect indoor air quality
u With Japanese semiconductor mix gas sensor inside. 5~7 years lifetime.
u High sensitive to contaminative gases and various kinds of odorous gases within the room (smoke, CO, alcohol, human odor, material odor).
u Two types available: indicator and controller
u Indicator is special design with six indicator lights to indicate six different IAQ levels.
u Temperature and humidity compensation makes the IAQ measurements consistent.
u One 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.
u Four setting CO level ranges selectable to control the relay output via a set of jumpers.
u Optional Modbus RS-485 communication interface, 15KV antistatic protection, independent address setting.
¨ Application
u Detect Indoor Air Quality
u Can be used in houses, offices, theaters, shops, restaurants, train stations and many other places
u Automatically ventilation control
u Detect Indoor Air Quality and transmit the detected IAQ level to other devices
u Optional Modbus communication interface
NOTE: F2000TSM-VOC series cannot be used as a safety detector, for example, gas alert detector.
