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