Description

  • Gravity HF Sensor (Calibrated) - I2C & UART
  • Detects Hydrogen fluoride (HF) concentration
  • Offers high stability and high sensitivity
  • Strong anti-interference ability
  • Adopts the electrochemical principle
  • Supports three output modes: analog, I2C, and UART

The Gravity HF Sensor (Calibrated) - I2C & UART detects hydrogen fluoride concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of hydrogen fluoride in the environment. It can be widely used in the detection of hydrogen fluoride in industrial and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years.
