Product Overview

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

Application Field

  • Hydrogen fluoride alarm
  • Hydrogen fluoride gas detection at industrial site
  • Mine hydrogen fluoride detection
  • Intelligent municipal hydrogen fluoride detection
  • Detection of hydrogen fluoride in atmospheric environment

Product Characteristics

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