Product Overview

THY - FDM Hydrogen Sulfide Gas Device is a high performance products, MCU, built-in OLED display, remote control, first adopted abroad in electrochemical sensor, advanced vlsi technology, proprietary digital to analog hybrid communications technology research and development. Its good stability, high sensitivity, fast response, long service life, has the communication and the advantages of the self-diagnosis function and convenient installation and maintenance, fully show the scene of the typical intelligent monitoring instrument now advanced performance, greatly satisfy the industrial view of safety monitoring of equipment reliability requirements. These products (gb GB12358-2006 workplaces environment gas detection alarming device general technical requirements)

 

Principle

Principles of solid state electrochemical detection. The principle is that two reaction electrodes, a working electrode and a counter electrode and a reference electrode are placed in a specific electrolyte, and then sufficient voltage is applied between the reaction electrodes to enable the REDOX reaction to be carried out through the gas under test coated with a thin film of heavy metal catalyst. The current generated by gas electrolysis is measured by the circuit system in the instrument, and then the gas concentration is calculated by the microprocessor.
