4HS-LM Hydrogen Sulfide Gas Sensor For Accurately Detect Concentration Of Hydrogen Sulfide Gas

• Product Usage:

It is mainly used to accurately detect the concentration of hydrogen sulfide gas. It is widely applied in various industries, including petroleum gas production and processing, chemical plants, refineries, fertilizer production, public facilities, sewage treatment, paper - making, pharmaceuticals, food and beverage, biogas, mining, military, etc., serving for safety detection, environmental monitoring, and production process control.

• Product Features:
  • High - precision Measurement: With a measuring range of 0 - 2000 ppm, it can provide relatively accurate hydrogen sulfide gas concentration measurement results, and the sensitivity is 0.09 ± 0.04 μA/ppm at 20°C.
  • Fast Response: The response time (T90) is ≤ 45 s, which can quickly respond to the change of hydrogen sulfide gas concentration, enabling timely detection and warning.
  • Good Stability: The baseline drift is < 10 ppm in the temperature range of - 40°C - 50°C, and the long - term stability is excellent, with a drift of < 2% of the signal value per month, which can ensure the reliability of long - term use.
  • Wide Operating Temperature Range: It can work normally in the temperature range of - 40°C - 50°C, and has strong adaptability to different environmental temperatures.
  • Good Environmental Adaptability: It can work in the humidity range of 15% - 90%RH (non - condensing), and is less affected by humidity. At the same time, it can work normally in the pressure range of 1 ± 0.1 atm.
  • Simple Structure and Light Weight: The housing is made of ABS material, with a weight of 5 g, which is small in size, light in weight, and easy to install and use.
  • Low Cross - Sensitivity: It has low cross - sensitivity to common gases such as carbon monoxide, ammonia, and hydrogen, and is less affected by other gases, which can ensure the accuracy of hydrogen sulfide gas detection.
