H2S Analyzer

  • Monitor hydrogen sulfide concentrations ranging from 0-10 ppm to 0-100% continuously using optical absorbance and eliminate the need to replace paper tape reels.


  • The H2S Analyzer system consists of two major components: the H2S Flow Cell and the PX2 Photometer. The flow cell, which can be connected to the process line, contains the sample so that it never comes into contact with the electronics. The PX2 is connected to the flow cell via fiber optic cables, and can be mounted away from the process in an area-specific enclosure for increased safety.


  • The PX2’s Auto-Tune feature takes the guesswork out of setting selection–fill the flow cell with zero/background gas and let the PX2 do all the work. Additional pressure and temperature outputs are offered to allow for measurement compensation.

Oil In Water Analyzer

  • Accurately measures the concentration of oil in water while producing results in real-time


  • Utilizes liquid-liquid extraction to eliminate background interferences in the sample


  • The AES Control Panel App allows the user to adjust the unit’s measurement, output, and logging settings; also allows the user to view historical data, export data to Excel as a .csv, and save or restore past measurement methods


  • The Auto-Tune feature automatically optimizes the measurement setting, while Auto-Cal determines calibration points using user-provided standards


  • Standard data outputs include MODBUS, 4-20mA, and USB to CST Software


  • Low cost of ownership with no routine maintenance
