KECO Solutions For Precise Acid Gas Detection
KECO offers advanced analyzers engineered for accurate, continuous measurement of hydrogen sulfide (H₂S) and carbon dioxide (CO₂) in challenging industrial environments.

Dual H2S & CO2 Gas Analyzer
The KECO Dual H2S & CO2 Gas Analyzer CS Hound is specifically designed for continuous, online monitoring of acid gas components such as hydrogen sulfide (H2S) and carbon dioxide (CO2). It uses electrochemical sensing for H2S and NDIR technology for CO2 detection. The sample gas is regulated to 10 PSI with a controlled flow rate of 1.5 SCFH to ensure precise measurement.
Fugitive Emission Control (Emission Eliminator)
The KECO Fugitive Emission Eliminator is designed to safely oxidize vented process gases, including acid gases like hydrogen sulfide, using a catalytic combustion system that maintains atmospheric pressure reference for analyzers. Operating with a continuous heat source, it converts over 99% of emissions into CO2 and water vapor. Housed in an explosion-proof enclosure, it enables safe deployment in hazardous environments where acid gas monitoring equipment is used.

H2S in Gas Analyzer (Electrochemical)
The KECO SulfurHound H2S in Gas Analyzer provides continuous, online detection of hydrogen sulfide within acid gas streams using reliable electrochemical sensor technology. The sample gas is regulated to approximately 10 PSI and maintained at a flow rate of 1.5 SCFH before entering the detection element, which generates a signal proportional to the H2S concentration.
H2S Analyzer
The KECO H2S Analyzer 100 (GP) and 200 (Div 1 & 2) deliver continuous, interference-free measurement of hydrogen sulfide within acid gas streams using the ASTM-approved lead acetate tape method. Sample gas is regulated to 10 PSI and passed through a precision flow meter before reaching a photometric sensor that quantifies H2S concentration. An onboard microprocessor digitizes the signal, providing a linear 4–20 mA output displayed on an integrated LCD with alarms and calibration prompts.

CO2 Process Analyzer
The KECO CarbonHound CO2 Process Analyzer provides continuous, online measurement of carbon dioxide, a key component of acid gas streams, using non-dispersive infrared (NDIR) technology. The gas sample is regulated to approximately 1.5 SCFH via a precision flowmeter before entering the IR sensor, which outputs a signal proportional to CO2 concentration. Data is processed by an onboard microprocessor and displayed on a color touchscreen with 4–20 mA output, alarms, and digital communication (RS-485, TCP/IP). Built with materials compatible with acid gas environments, the system ensures accurate, reliable, and low-maintenance CO2 monitoring critical to acid gas analysis and control.
