A hydrogen sulphide sensor, often known as an H2S sensor, is a gas sensor that measures hydrogen sulphide. To provide a safe working environment, H2S sensors look for harmful quantities of hydrogen sulphide gas.
The following are examples of typical settings where gas sensing, detection, and monitoring are essential: Oil refineries. municipal wastewater treatment plants. Hydrogen sulphide is measured by the monitor in parts-per-billion (ppb) or parts-per-million (ppm) (ppm).
When the gas makes contact with the sensor and causes an electrochemical reaction, the device measures the amount of H2S in the air. As a result, a tiny electrical current is generated, giving the sensor a reading.
The Global Hydrogen sulfide sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
City Technology introduces the 7HH/LM, a hydrogen sulphide sensor with reduced cross-sensitivity to methanol. The 7HH/LM CiTiceL®, a novel, high-sensitivity hydrogen sulphide sensor with reduced cross-sensitivity to methanol, is now available, according to City Technology (Plate 15).
It delivers a significant performance improvement over its regular CiTiceL equivalents and is the product of a lengthy development effort at City’s dedicated research lab in Portsmouth, UK.
This high output sensor is perfectly suited for integration into permanent and portable safety devices used in settings where organic or alcoholic vapours are present in the background. In de-icing agents, methanol is frequently employed as a solvent in cold conditions with temperatures as low as 40°C.
Standard H2S sensors are susceptible to cross-sensitivity to methanol and related alcohols in such applications, which can result in expensive false alarms.
However, this new CiTiceL exhibits very little activity for methanol oxidation thanks to a changed formulation of the sensing electrode. Additionally, changes have been made to the internal architecture to reduce alcohol migration to the reference electrode.
The 7HH/LM can easily be swapped out for conventional 7 Series sensors because it is available in the 7 Series small format. OEMs may be sure from the start of the sensor’s robustness and good performance thanks to its proven patented design.
