KGD - MQ - 517 Ultraviolet Hydrogen Sulfide Analyzer Product Introduction The KGD - MQ - 517 Ultraviolet Hydrogen Sulfide Analyzer is a new -
generation hydrogen sulfide analyzer independently developed based
on ultraviolet absorption spectroscopy gas analysis technology. It
adopts a unique algorithm and a high - precision gas cell, with
strong anti - interference ability and high measurement accuracy.
It has a selectable measurement range and good stability, and can
replace the electrochemical gas analysis technology with a short
service life and easy wear, as well as the gas chromatography
technology which is expensive and unable to perform real - time
monitoring. Product Features - High accuracy. Using ultraviolet absorption spectroscopy gas
analysis technology, it can conduct real - time on - line
monitoring and reduce gas cross - interference.
- Measurement range: Can be customized according to customer
requirements.
- Strong corrosion resistance. Parts in contact with the sample gas
are all 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.
- Can replace electrochemical gas analysis technology and gas
chromatographs, with a long service life, high cost - performance
ratio, and low maintenance cost.
