Product Overview

This is a high-performance product featuring an integrated MCU, OLED display, remote control operation, and utilizes the DS4 intelligent gas sensor, advanced ultra-large-scale integrated circuit technology,

Developed with proprietary digital and analog mixed communication technology, it boasts excellent stability, high sensitivity, rapid response, long service life, communication and self-diagnostic functions, and easy installation and maintenance.

Principle of Testing

High humidity resistance, long service life, anti-toxicity, and high reliability—suited for use in harsh working conditions.

Principle of electrochemical detection. It involves placing two reaction electrodes (a working electrode and a counter electrode) and a reference electrode in a specific electrolyte solution.

Then, apply sufficient voltage between the reaction electrodes to enable the oxidation-reduction reaction of the test gas permeating through the heavy metal catalyst film.

Measure the current generated during gas electrolysis through the circuit system of the instrument, and then the microprocessor calculates the gas concentration.
