Product Overview

S4-H2O2   The hydrogen peroxide gas detection sensor is a constant potential electrolytic sensor. The electrochemical oxidation process of hydrogen peroxide on the working electrode is to keep the working electrode and the reference electrode of the electrolytic cell at an appropriate potential through the electronic circuit. At this potential, the electrochemical oxidation or reduction of hydrogen peroxide can occur. The concentration of the gas to be measured can be determined by measuring the current.

Application Field

  • Hydrogen peroxide generator
  • Medical hydrogen peroxide disinfection
  • Smart municipal hydrogen peroxide detection
  • Hydrogen peroxide detection in atmospheric environment

Product Characteristics

  • High precision and long service life 
  • Fast response speed, fast return to zero 
  • Low power consumption, high sensitivity
  • Wide linear range
  • Excellent repeatability and stability
  • Strong anti-interference ability
