H2S Analyser for High and Low Concentrations of Hydrogen Sulfide
The H2S-220 is a diode array UV fiber optics process spectrometer. It is designed to address on-line applications that require reliable, accurate, rugged and maintenance free monitoring of H2S concentration. Either a fiber optics insitu probe or flow cell can be used.
A bifurcated fiber optics cable is used to conduct light to and from the probe or flow cell. The insitu probe is inserted into a sintered metal filter to protect it.
The flow cell path length depends on the H2S concentration range and range from 2 mm to 1 meter.
While a variety of flow cells optical paths and materials of construction are offered two basic standard sampling system designs are offered; An extractive aspirated system with a manual or automatic zero for gases and liquids, and a closed coupled extractive stack sampler with flow indication and automatic zero capability.
An industrial PC is used for data processing and user interface. The H2S-220’s user-friendly interface allows for modification of operational parameters including sampling system’s relays (no need for a PLC) , all the parameters can be modified through a touch screen interface.
