CES-Landtec GA-90 (L) Methane(CH4) O2-CO2 Analyzer

CES-Landtec's GA-90 is a compact field instrument designed to analyze Methane (0 to 100%), Carbon Dioxide (0 to 50%), and Oxygen (0 to 21%) levels in landfill gas through infrared absorption. The notebook-sized instrument introduces computer technology that uses instruction menus to simplify accurate data analysis and recording while eliminating the need to carry as many as six separate instruments (CH4, CO2, O2 analyzers, barometer, static pressure meter, datalogger and sample pump). The collected information is date and time stamped, and as many as 1,200 readings can be stored in memory for future downloading to a printer or PC. Also features adjustable alarms, unattended auto-logging functions and flow-fail alarm.
