Tongdy
TSP-CO-B100
Carbon Monoxide Transmitter and Controller
The TSP-CO Carbon Monoxide Transmitter and Controller provides continuous monitoring of carbon monoxide levels in commercial and industrial environments where air quality and safety are critical.
Note: All Tongdy monitors and controls ship direct from the factory. Please allow 10-15 business days for shipping and handling.
It measures CO concentration in real time and can also monitor ambient temperature, helping facility managers maintain safe air conditions while controlling ventilation systems efficiently.
The unit uses a high quality Figaro electrochemical CO sensor that delivers stable, accurate measurements with a service life of more than five years. The sensor module is replaceable, which helps reduce maintenance costs and extend the overall life of the instrument. Flexible outputs include a 0 to 10V or 4 to 20mA analog signal for integration with ventilation controls, environmental monitoring systems and building automation platforms.
RS485 communication with Modbus RTU protocol allows easy integration with modern building management systems. Relay outputs can be used to activate ventilation fans, alarms or other safety devices when carbon monoxide levels reach preset thresholds. A three color status indicator provides quick visual confirmation of operating conditions while an optional buzzer alerts personnel when CO levels exceed the alarm setpoint.
The transmitter is housed in a durable industrial grade PC and ABS enclosure designed for reliable operation in demanding environments such as parking garages, mechanical rooms and ventilation control systems. When properly installed the unit can monitor air quality across an area with a coverage radius of up to approximately 30 meters depending on airflow conditions.
