Description

The pipeline, geothermal, paper mill, municipal sewage, drilling, & personnel protection industries has for many years needed a dependable, efficient, and cost effective trend H2S analyzer for quality and process control purposes. Now, Analytical Systems Intl. has met these requirements with a proven microprocessor based technology which provides continuous on line analysis based on the electrochemical principal of operation. The gas being analyzed for H2S is regulated to 10 PSI, then a flow meter regulates the flow to aprox. 1 SCFH. Next, the sample is introduced to the electrochemical detection element which provides an output proportional to the concentration of H2S. The signal is then digitized and analyzed by the advanced microprocessor and related software. The LCD display and electronics provides the current reading, previous reading, cycling time, any alarm condition, procedure prompts (such as calibration procedure), and failure indicators (local and remote capability). The analyzer can also interact, communicate, and transmit information for other manufacture's instrumentation. Quality materials are selected for their compatibility and are utilized throughout fabrication. Special attention is given to wetted parts that come in contact with the process stream and are selected to be non reactive.
