Electrochemical H2 Hydrogen Sensor FS02500 Introduction
FS02500 is a fuel cell type electrochemical sensor that works by an oxidation or reduction reaction occurring on its working electrode and counter electrode, releasing charged ions and creating a current. The magnitude of the current produced is proportional to the concentration of hydrogen and follows Faraday’s law. By measuring the size of the current, the concentration of hydrogen can be determined. The sensor uses high-stability gas sensors and high-performance microprocessors and supports UART output and Modbus-RS485 output. The module is calibrated and tested using precision automated calibration and detection equipment to reduce human interference, ensuring accurate and consistent data while also ensuring large-scale production efficiency.
