//Final CO2 sensor transmitter

CO2 sensor transmitter

Tongdy F12 CO2 transmitter

The Tongdy F12 CO2 transmitter uses a NDIR infrared detector to provide real time readings of the CO2 levels via a 4~20ma or 0-10vdc output. These sensors can be connected to any control device that can effectively measure 0-10vdc or 4~20ma signals. They also have an optional Modbus output for communication to building management systems and PLC’s.

CO2 monitor & controller

Tongdy F2000IAQ CO2 controller

F2000IAQ-CO2 monitor/controller is used to monitor and control, room CO2 levels, as well as room temperature and humidity. It provides one, two or three 0~10vdc analog outputs and up to three dry contact outputs . F2000IAQ-CO2 can be as a programmable logical controller to control CO2 level, temperature or humidity, and also as a transmitter DDC/PLC controller or other automation systems. It provides a RS485 communication interface with an independent address to PC or other control systems.

CO2 monitor & controller

Tongdy GO1 CO2 monitor & alarm

The Tongdy GO1 CO2 controller uses a NDIR infrared detector to provide real time readings of the CO2 levels via a 4~20ma or 0-10vdc output. It has the option to provide temperature as well as relative humidity readings on separate analogue outputs. The current CO2, temperature and RH readings are displayed on the LCD screen.
