Keco SulfurHound Electrochemical H2S Analyzer

SulfurHound is a continuously operating, microprocessor-based electrochemical H2S analyzer. The sample is regulated to about 10 PSI and set to a flow of 1.5 SCFH with a flow meter; the detector produces a signal proportional to H2S concentration, which the microprocessor digitizes. It is used to measure H2S in natural gas, biogas and air at gas processing, pipeline, chemical and landfill gas plants.

• Requires no paper tape, solution or scrubber.
• Designed for Division 2 and Zone 2 hazardous areas.
• Color touchscreen shows current and past values, graphs, alarms and calibration warnings.
• Can calibrate automatically; few moving parts, low maintenance need.
• Wetted materials selected not to react in H2S service.

Those preferring the tape method can look at Model 100/200, and Model 800 for total sulfur; CarbonHound measures CO2 and MethaneHound CH4.

With no tape consumable, it has advantages in operating cost and maintenance frequency at remote, rarely visited sites such as biogas units and pipeline stations. Remote monitoring software lets fault conditions be seen centrally.

Tetra plans electrochemical cell life and calibration interval according to operating conditions, connects Modbus and 4-20 mA outputs to the DCS and carries out verification visits with calibration gas.
