Description

Gastec HS-100 Hydrogen Sulphide Sensor

Gastec HS-100 (also cataloged as HS100) is an electrochemical replacement sensor module engineered for Gastec portable gas detection units and continuous monitoring monitors.

It provides real-time measurement of toxic Hydrogen Sulphide ( $\text{H}_2\text{S}$ ) gas, typically calibrated for standard personal protection and breathing zone monitoring ranges ( $0.0\text{ to }30.0\text{ ppm}$ or $0.0\text{ to }50.0\text{ ppm}$ ).

Gas sensors

GASTEC is engaged in research and development of world-leading catalyst technology and power collection technology, and has realized a variety of highly sensitive, miniature sensors. These sensors detect the concentration of oxygen concerning which even a minute percentage change can affect the human body. They can also detect colorless and odorless toxic gases which cannot be detected by the five senses, and flammable gases which can bring about an explosion or other disaster. In this way, we promote the ability to visualize danger.
