SGX-BR2-5

Bromine sensor SGX-BR2-5 Datasheet SGX Liquid Electrochemical Gas Sensors These SGX Sensors use a revolutionary innovation in electrochemical sensing, which detects the output signals from the electrochemical reactions of different gases. Furthermore, it accurately measures gas concentration through the magnitude of the signal. These specialised sensors consist of three catalytic electrodes, liquid electrolyte and gas diffusion holes. Through the diffusion holes, the gas reaches the sensor's working electrode, where an electrochemical reaction takes place at the so-called 3-phase boundary. A current signal is generated at the output, which is linearly proportional to the gas concentration. Quality, Safety, Responsibility SGX Europe Sp. z o.o.
