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.


Portable and fixed gas detector, various gas detection equipment and situation.


  1. High sensitivity & resolution
  2. Low power consumption
  3. UART and analog voltage output
  4. Good stability and excellent anti-interference ability
