The Model 100 & 200 is a proven H2S gas analyzer designed for continuous, real-time measurement of hydrogen sulfide in gas streams. For full product specifications, refer to the KECO H2S analyzer page. This system uses ASTM-approved tape-based detection to deliver accurate, interference-free measurement from ppb to percent levels. It eliminates false positives and ensures stable performance, providing operators with confidence in safety-critical and process control applications.
Unlike traditional sensor technologies, this system utilizes a rateometric colorimetric tape principle that is specific only to hydrogen sulfide. This prevents cross-interference from other components in the gas stream, eliminating false alarms and improving measurement reliability. The analyzer automatically regulates sample pressure and flow, delivering consistent and repeatable performance across a wide range of operating conditions.
For applications requiring complementary gas composition monitoring, systems such as the Methane Gas Analyzer can be used alongside H2S measurement to provide a more complete understanding of gas quality.
The Model 100 & 200 provides continuous online monitoring with fast response times and automatic self-zero functionality. It delivers stable, drift-free measurement while supporting integration into plant control systems through standard outputs such as 4–20 mA and digital communications.
For applications where CO2 monitoring is also required, solutions such as the CarbonHound CO2 Gas Analyzer can complement H2S measurement in biogas, natural gas, and process applications.
Accurate H2S measurement depends on clean, representative samples. In systems where liquids or contaminants may be present, integrating upstream protection such as the Liquids Carryover Sensor helps protect the analyzer and maintain measurement reliability.
For fast-response applications, integrating the Fast Sample System FSS-1 can improve sample transport speed and overall system performance.
Engineered for long-term performance, this H2S gas analyzer minimizes maintenance through automatic calibration, extended tape life, and robust construction. The explosion-proof design of the Model 200 supports safe operation in hazardous environments, while remote monitoring capabilities provide additional flexibility.
With thousands of installations worldwide, it delivers dependable performance in demanding industrial applications, helping reduce downtime, lower operating costs, and improve measurement confidence.
