How does a H2S sensor work?
Electrochemical Detectors H2S diffuses through a permeable membrane, the volume of H2S increases in the air, an oxidation or reduction reaction occurs at one of the electrodes, and as a result, a linear current change occurs. This enables a display or an amplifier device to generate an indication of the H2S level.
What is the working principle of gas detector?
Electrochemical. Electrochemical gas detectors work by allowing gases to diffuse through a porous membrane to an electrode where it is either chemically oxidized or reduced. The amount of current produced is determined by how much of the gas is oxidized at the electrode, indicating the concentration of the gas.
How is H2S monitored?
Test (monitor) the air for hydrogen sulfide. This must be done by a qualified person. Use the right test equipment, such as an electronic meter that detects hydrogen sulfide gas. Conduct air monitoring prior to and at regular times during any work activity where hydrogen sulfide exposure is possible.
What are the different types of H2S detectors?
Hydrogen Sulphide Gas Detectors (H2S)
- TOC-750X Explosion Proof Addressable Gas Detector.
- Portable Hydrogen Sulphide Gas Detector.
- Confined Space 4 Gas Monitor – MGT.
How does an H2S sensor work?
An H2S Sensor generates a current output equivalent to the PPM level of H2S that diffuses into the sensor through a hydrophobic membrane. The H2S Sensor hydrophobic membrane allows gas to permeate through to the sensor electrolyte, while protecting the sensor from liquids.
What is the H2S sensor hydrophobic membrane?
The H2S Sensor hydrophobic membrane allows gas to permeate through to the sensor electrolyte, while protecting the sensor from liquids.
What is an H2S meter used for?
An H2S Meter used for personnel safety monitoring of ambient areas includes PLC or DCS system alarm annunciation. It may also have audible and visual alarm device local annunciation to alert personnel in an area that the level of H2S detected by the H2S Sensor are above hazardous levels.
Is the rs-h2s-*-2-100p H2S sensor dust-proof?
The RS-H2S-*-2-100P H2S sensor is wall-mounted, the housing is dust-proof and waterproof, with a long using life. IP65 protection grade, can work normally in harsh environments.
