Product Description

This H2S gas analyzer is accurate (PPB levels and up), dependable (no “false positives”) and low-maintenance. All of which are greatly needed in the the petrochemical, gas processing, and gas pipeline industry for quality and process control purposes. With over thirty years of experience in developing and manufacturing H2S analyzers and associated parts and supplies, KECO has met these requirements with their proven microprocessor based natural gas H2S analyzer. This hydrogen sulfide (H2S) analyzer or monitor provides continuous on-line process analysis based on the specific and interference free ASTM approved tape principle of operation.

The process stream is regulated to 10 PSI by the provided pressure regulator. Then a precision flow meter on the analyzer regulates the sample flow and is humidified. Next, the sample is introduced to the specific lead acetate sensing tape that provides an output proportional to the concentration of H2S analyzer through the photodiode detector and LED light source optical system. This signal is digitized and analyzed by the advanced microprocessor and related software resulting in a linear 4-20 mA output. The LCD display provides the current reading, any alarm condition, procedure prompts (i.e. calibration), and failure indicators. Quality materials are selected for compatibility and are utilized throughout the manufacturing process.

This reliable and field proven H2S analyzer system continuously and specifically quantifies the H2S levels in the sample with minimal maintenance. The principle of operation is described in various ASTM methods include D4084-82, D4468-85, and D4045-81.

The rateometric-colorimetric tape detector offered by KECO is the only H2S detection method that is free from cross-interference and will not suffer from “false positives” like other H2S analyzer methods. Users demand KECO’s H2S analyzer due to its precision and reliability proven by thousands of worldwide installations around the globe.
