Works Great NR comes with AC Charger!CES Landtec Landfil Gas Monitor Meter CH4 COPortable, Computerized Instrument Simplifies Landfill Gas AnalysisAccurate landfill gas (LFG) analysis is essential in meeting today's strict environmental and safety regulations. The GA 90 is a compact field instrument which can be configured to analyze the methane (CH4), carbon dioxide (CO2) and oxygen (O2) levels in LFG. It is used by landfill field technicians in monitoring migration probes, active and passive gas extraction systems and measuring LFG at flares or other control systems.The GA 90 introduces computer technology that uses on-screen menus to provide a simplified user interface for accurate data analysis and recording while eliminating the need to carry as many as seven separate field instruments depending on the features selected (CH4 CO2 02 analyzers, barometer, static pressure meter, data logger, temperature gauge and sample pump). The collected information is date and time stamped and readings are stored in memory. Later, the data can be downloaded to a personal computer or printer to provide error-free data management. These features result in faster, more reliable monitoring.Multi-Functional FeaturesLCD screen menus prompt the technician through sampling and analysis of the methane, carbon dioxide and oxygen content of landfill gas and recording the static and barometric pressures. Alarms can be easily set to monitor for high methane and carbon dioxide or low oxygen levels. The GA 90 also can display the CH4 concentration in % by volume or % LEL (Lower Explosive Limit) of methane. The automatic data logging function allows unattended sampling and analysis of gas concentrations and atmospheric pressure. Results can be displayed in either Imperial (USA) or SI (metric) units.The GA 90 can store over 1000 sets of measurements (each measurement stores three gas concentrations, atmospheric pressure and static well pressure plus temperature) with a date and time stamp plus sample I.D. code.The measurements may be viewed on the GA 90screen, printed or downloaded to a PC computer.TopRugged, Compact, User--Friendly DesignThe GA 90 is an all-weather, notebook-sized instrument that uses a self-compensating, infrared bench, long-life galvanic cell oxygen sensor, high vacuum gas sample pump and rechargeable power supply. An easy to follow, on-screen menu simplifies use, guiding the operator through the sampling process, that can usually be completed in minutes. I.D. codes allow the user to store and recall measurements for each monitoring point. An optional cable and PC software allow easy downloading of stored data to a personal computer for further analysis and report generation. The same cable can be used to print directly to a printer. GA 90 FeaturesMulti-Functional Analyzer...provides automatic sampling and analysis of gas composition CH4 (0-100% and LEL), CO2, (0-60%) and 02 (0-25%).Light-Weight Compact Size...is easy to carry. It is the size of a notebook and weighs less than five pounds.Quick Analysis...samples, analyzes and displays gas composition results in usually less than one minute.Infrared Bench...provides accurate measurements of CH4 and CO2 and is not poisoned by the presence of other gases.Durable Oxygen Sensor...is a galvanic cell unaffected by other gases such as CO2, CO or H2S.Field Calibration...allows for improved accuracy.

An infrared beam is projected, via sapphire windows, through the gas sample. On the other side of the chamber the beam is sensed by methane and carbon dioxide detectors. A microprocessor calculates the amount of infrared light absorbed at different wavelengths and determines the various gas concentrations.The oxygen concentration is measured by the Galvanic Cell method. The oxygen molecules diffuse through a Teflon membrane into a cell containing a gold electrode. The molecules are reduced and a current flows between the gold electrode and a lead electrode. The resulting cell output is measured as a voltage which is proportional to the oxygen concentration. The entire system has a very high resistance to poisoning caused by the presence of other gases, such as carbon dioxide or hydrogen sulfide.When a sufficient amount of gas has entered the sample chamber, gas concentration levels shown on the display will stabilize. A few keystrokes will store the measured data in the GA 90 memory with I.D. code, date and time.GA 90 Sample ResolutionMethane (CH4); Sensor Range : 0-100%, Resolution 0.1%Carbon dioxide (CO2): Sensor Range: 0-60%, Resolution 0.1%Oxygen(O2) Sensor Range: 0-25%, Resolution: 0.1%Static Pressure: Sensor Range: 0-100" H2O, Resolution 0.11" H2OBarometric Pressure Sensor Range: +-0.15" Hg, Resolution: 0.1" HgItem is in good physical condition.Item powers up and displays the info on the screen "unit not covered by lifetime guarantee, next service due...product Includes Landtec GA-90, red cloth carrying case, 5 ft.
