DS4-H2S-100 Electrochemistry Gas Sensor

Detection Principle:

Utilizes solid polymer electrochemical sensing technology based on the principle of electrochemical catalytic reaction. The sensor consists of three catalytic electrodes, a solid electrolyte, and gas diffusion holes. Gas reaches the working electrode through the diffusion holes, where electrochemical oxidation or reduction reactions occur on the porous micro-surface of the electrode. The solid electrolyte conducts electron transfer, outputting a current signal proportional to the gas concentration.

Features:

• Standard industrial size for easy installation and integration.
• No preheating required, ready for immediate use.
• Low-power sleep mode for battery-powered and power-sensitive applications.
• Factory-precalibrated for precision; no user calibration needed.
• User-definable encryption codes to prevent misinsertion of other sensor types.
• Self-identification capability for system integration.
• Easy maintenance, reducing operational and maintenance costs.
