ZE03 is a general-purpose and high-performance electrochemical module. It uses three electrodes, electrochemical gas sensor and high-performance micro-processor. By installing different gas sensor, the module could detect relevant gas. It is with built-in temperature sensor to make temperature compensation, which makes it could detect the gas concentration accurately. It has the digital output and analog voltage output at the same time which facilities the usage and calibration and shorten the development period. It is a combination of mature electrochemical detection principle and sophisticated circuit design, to meet customers’ different detection needs.
MP-4 model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas exists , The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, convert change of conductivity to correspond output signal of gas concentration.
