DS4-CH4S Intelligent Digital Gas Sensor
Overview:
The DS4-CH4S methyl mercaptan (CH₄S) intelligent digital sensor is developed by AQS (Aikesen Technology), a company specializing in gas detection solutions. Its core technical team has over 20 years of expertise in gas detection technology and applications.
Technical Principle
Based on solid polymer electrochemical sensing technology, a revolutionary innovation in electrochemical detection. The sensor consists of three catalytic electrodes, a solid-state electrolyte, and gas diffusion pores. Gas reaches the working electrode through diffusion pores, where electrochemical oxidation or reduction occurs on the porous micro-surface. The solid-state electrolyte enables electron transfer, generating a current signal proportional to the gas concentration.
