Product name: UV H2S analyzer
Product model: AL3000UV
It is a new generation of hydrogen sulfide analyzer independently developed based on the world's leading ultraviolet absorption spectrum gas analysis technology. Adopt unique algorithm, high-precision gas chamber, strong anti-interference ability, high measurement accuracy; selectable range, good stability, can replace short-lived, easy-to-wear electrochemical gas analysis technology and expensive gas chromatography that cannot be monitored in real time technology.
High precision, using ultraviolet absorption spectrum gas analysis technology, real-time online monitoring, reducing gas cross-interference
· With reference gas chamber, measurement is more accurate
· Range: can be customized according to customers. It can measure 500ppm of H2S before desulfurization and 30~50ppm of H2S after desulfurization.
· Strong corrosion resistance, the parts in contact with the sample gas are made of corrosion-resistant materials
· Built-in automatic zero adjustment air pump, which can realize automatic air zero adjustment
· Data can be transmitted to the superior centralized control system through multiple interfaces
· It can replace electrochemical gas analysis technology and gas chromatograph, with long life, high cost performance and low maintenance cost
