Product Details
AHS3000 Potentiometric Electrolytic Hydrogen Sulfide Gas Sensor For
Hydrogen Sulfide Detection In Industrial Sites
- Product Uses: It is mainly used for hydrogen sulfide detection in
industrial sites and environmental protection fields. It can be
installed in portable hydrogen sulfide detection instruments and
fixed - point hydrogen sulfide detectors, and is applicable to
scenarios such as coal low - temperature coking, sulfur -
containing oil extraction and refining, rubber, leather, dye, sugar
production and other industrial production processes, as well as
operations such as excavation and renovation of swamps, ditches,
printing and dyeing, sewers, tunnels, and garbage and feces
removal. It is used to accurately detect hydrogen sulfide to ensure
people's health and safety.
- Product Features:
- Small Size: It has a compact structure, which can be easily
integrated into portable instruments, facilitating installation and
use in various small - sized detection equipment.
- High Sensitivity: The sensitivity can reach 700±150 nA/ppm, which
can quickly and accurately detect the change of hydrogen sulfide
concentration, and can respond to very low - concentration hydrogen
sulfide gas.
- Fast Response: The response time (T90) is ≤30 s. Once calibrated to
a known concentration, it can quickly output repeatable and
accurate target gas values within 30 seconds, which is conducive to
timely detection of hydrogen sulfide gas and timely response.
- Stable Output Signal: It has excellent long - term stability, can
maintain stable performance in a wide temperature range (- 40℃ ~
55℃), and is less affected by the environment, ensuring the
accuracy and reliability of detection results.
- Replaceability: It can directly replace the same - type three -
electrode hydrogen sulfide sensors on the market, providing
customers with a high - quality and low - cost hydrogen sulfide
detection solution, which is convenient for product upgrading and
maintenance.
