    １１．Detection principle NDIR method (Non-Dispersive Infrared) １１－１ ． The model is based on NDIR method (Non-Dispersive Infrared) and this structure is shown below. The infrared beam emitted from the light source passes through the measuring cell, and optical band pass filter which can pass the absorption wave of measuring gas and attains to the infrared sensor.

  • Page 34: １１－３．Electro-Chemical Cell Method

    １１－３．ELECTRO-CHEMICAL CELL method This gas detector applies an electrochemical sensor. The sample gas is electrolyzed by the electrolyzed cell added with specific electric potential (bias voltage) and detected from the electrolyzed current generated at that time. The electrochemical sensor is designed to keep the interface between electrode and electrolyte at a constant potential (Bias voltage) and is the method to electrolyze gas directly.
