Detcon Model P-1000-H2S is a portable gas analyzer designed to provide accurate measurement of Hydrogen Sulfi de gas concentrations in natural gas wells, natural gas pipelines and in the outlet from natural gas treating plants. The portable battery powered instrument utilizes advanced electrochemical sensor technology and microprocessor based electronic control circuitry that includes a built-in portable data logger. Stored data can be downloaded to a spreadsheet and used to create trend graphs, average readings and peak values. A universal signal conditioning circuit with an LCD display and any one of three intelligent sensor modules can be combined to provide ranges of�measurement 0-20 PPM, 0-100 PPM or 0-1000 PPM. The analyzer sensor and control circuitry are mounted in a weatherproof enclosure with a built-in battery supply and secondary sample conditioning components. Model P-1000-H2S is capable of continuous operation for a period of approximately 30 days before battery recharge is required. The intrinsically safe design is suitable for hazardous area usage.
