Application Characteristics of Hydrogen Sulfide Gas Detectors and How to Select Them
The hydrogen sulfide gas detector adopts imported original Ampere type electrochemical sensors, usually consisting of three electrodes immersed in electrolyte. The working electrode is made by coating a metal with catalytic activity on a breathable but hydrophobic membrane. The measured gas diffuses through a porous membrane and undergoes electrochemical oxidation or reduction reactions on it. The nature of the reaction depends on the thermodynamic potential of the working electrode and the electrochemical (oxidation or reduction) properties of the analyzed gas.
Selection guide for hydrogen sulfide gas detector
1. Applicability. The application scope of different gas detectors also varies. For example, industrial gas detectors need to comply with various national safety standards and are more complex to use. Gas detectors used in ordinary households are relatively simple and can generally be used by plugging in a power source.
2. Reliability. General operators will take corresponding safety measures based on the detection data of the gas detector. If the gas detector is unstable and the detection results have significant deviations, it will directly pose a threat to personnel's life safety.
3. Stability. Anyway, the more accurate the monitoring data of the gas detector, the better, and the smaller the zero offset and full range offset values, the more advantageous it is.
4. Convenience. Convenience is also an important factor to consider when choosing a gas detector. For example, some construction workers may frequently change construction sites and may need to carry the gas detector with them. In this case, the convenience of using the gas detector becomes particularly important.
