Hydrogen Sulphide Analyzer(H2S Analyzer)

The PX2+ Photometric Transmitter utilizes Beers Law (the absorbance of light as it passes through a substance) at a specified wavelength to monitor changes in the concentration of an analyte in process. It sends optical radiation from a source within the instrument out to a flow cell and returns the signal to the instrument via fiber optic cable. The path length of the flow cell can be factory set at 0.1 cm. up to 3 meters to monitor concentration ranges as high as 0-100% or as low as 0-10ppm. The signal is linearized, and the resulting analog or digital signal can be sent to a PLC or DCS for process control.

The PX2+ Control Panel App allows the user to adjust the unit’s measurement, output, and logging settings. The Auto-Tune feature automatically optimizes the PX2+’s measurement setting for a particular application, while Auto-Cal determines calibration points using user-provided standards. The PX2+ Control Panel App also allows the user to view historical data, export data to Excel as a csv, and save or restore past measurement methods.

• Wide Range: monitor 0-100% or as low as 0-10ppm
• Auto-Tune: fill the flow cell with zero gas and let Auto-Cal determine the optimal settings.
• Pressure/Temp Correction: dedicated outputs for pressure/temp allow for automatic measurement correction.
• Robust: 3000psi max at inlet, regulated down to 500 psi max within the flow cell.
• 1 Consumable: Xe light source typically lasts ~5 years.
• Solid State: no moving parts; gas is brought directly from process and analyzed in flow cell.
• Fiber Optic Sample Interface: only the sealed optics contact the sample; since the electronics are connected to the sample interface via fiber optic cable, the electronics can be installed away from the process.
