fixed infrared carbon dioxide detector transmitter KB-502X
Carbon dioxide detector KB-502X is particularly applicable for the building system. There are two optional output modes which make the device convenient to be installed and operated, including analogue circuit / voltage output and one-way relay output. In heating and ventilating field, this device is widely applied for controlling the ventilating by detecting the carbon dioxide concentration. By this way, the energy can be saved at least 30%. It used imported advanced infrared sensor, which has high stability and reliability.
