Electrochemical H2S Hydrogen Sulfide Gas Sensor FS01700 Introduction
FS01700 is a fuel cell type electrochemical sensor that works by the oxidation and reduction reactions on the working electrode and counter electrode, releasing charges to form a current. The magnitude of the current generated is proportional to the concentration of hydrogen sulfide and follows Faraday’s law. By testing the magnitude of the current, the hydrogen sulfide concentration can be determined. It uses a high-stability gas sensor and a high-performance microprocessor that supports UART output and Modbus-RS485 output for easy use. The module adopts precise automatic calibration and detection equipment, reducing human interference and ensuring the accuracy and consistency of data during large-scale production.
