Product Overview

S4-THT  tetrahydrothiophene gas detection sensor is a constant potential electrolytic sensor. The tetrahydrothiophene and oxygen will undergo the corresponding redox reaction on the working electrode and the counter electrode and release the charge to form a current. The generated current is proportional to the concentration of tetrahydrothiophene. The concentration of tetrahydrothiophene can be determined by measuring the current.

Application Field

  • Tetrahydrothiophene Detector
  • Tetrahydrothiophene Detection at industrial site
  • Tetrahydrothiophene Detection in pharmaceutical field
  • Tetrahydrothiophene Detection for municipal administration
  • Tetrahydrothiophene Detection in farming industry

Product Characteristics

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