Highlights
- Diverse Field Applications-monitors migration control systems, gas extraction systems, flares, migration probes, and more.
- Gas Extraction Monitor Mode-provides automatic sampling and analysis of gas composition % by volume CH4, CO2, O2 and % balance gas, % CH4LEL, temperature (with optional probe), static pressure, differential pressure, and barometric pressure. Also calculates gas flow rates (SCFM) as well as Btu rates.
- Landfill Gas Analyzer Mode-provides automatic sampling and analysis of gas composition % by volume CH4, CO2, O2 and % balance gas, % CH4LEL, temperature (with optional probe), barometric pressure and relative pressure. Can be used for data logging, with user programmed intervals.
- Easy To Read Display-extra large backlit LCD shows up to five gases, atmospheric and gas vacuum pressure, temperature, ID code-all at the same time.
- Intrinsically Safe-essential for protecting personnel who work with explosive and hazardous landfill gas.
- On Site Calibration-rapid calibration checking or adjustment can be carried out on site.
- Automatic Purge-automatically purges analyzer with clean air when a new ID is selected. (This feature can be turned off).
- Light Weight Compact Size-easy to carry. Weighs less than five pounds.
- Quick Analysis-completes sampling and displays gas analysis and flow results in less than one minute.
- Infrared Gas Analyzer- provides accurate measurements of methane (CH4) and carbon dioxide (CO2).
- Gas Temperature-read when using optional temperature probe or can be entered manually.
- Durable Oxygen Sensor-provided by the galvanic cell principle, not influenced by other gases (i.e. CH4, CO2 or H2S)
- User Friendly On-Screen Menu-in each mode the user performs most operations in just two screens.
- PC Data Downloading-provided by RS232 interface with Data Field software (Release 3.0 or later).
- Data Storage/Retrieval-stores prior measurements take for each monitoring point, 900 monitoring points total.
- Date/Time Stamp-recorded for all stored data.
- Prior Data Recall-allows user to view prior data for each monitoring point.
- Methane Analysis-displayed as either % CH4 by volume or CH4LEL (Landfill Gas Analyzer Mode Only).
- Durable Construction-Built strong, durable plastic material suitable for harsh landfill environments.
- All Weather Use-designed to operate in extremes from 32F to 104F. Sealed, weather-tight case.
- Built-in Adjustable Alarms-allows user to set alarm limits for CH4 and O2.
- Rechargeable Batteries-internal, rechargeable nickel metal hydride batters are standard.
- Operating Time- approximately 8 hours with normal pump usage (approximately 10 hours without pump running.)
- Fast Recharge Time-approximately 2 hours from complete discharge.
- Battery Check-battery life is continuously displayed.
- Monitoring Point ID Codes-provides alphanumeric identification of monitoring points for data storage and recall.
- ID Comments- allows user to answer up to 3 questions with a list of 9 potential answers each.
- Imperial vs. SI Units- can display measurements in Imperial (USA) or SI (metric) units.
- Interfaces to CES-LANDTEC- Data Field software, which provides statistical management and reporting of LFG data.
- Multiple Flow Meter Analysis- calculates gas flow with Accu-Flo wellheads, orifice plates and pitot tubes.

*NOTE: All Organic Vapor Analyzers (PID, FID, TLV Sniffer) and Gas Meters are calibrated prior to each rental. If you wish to purchase calibration gas, please call for pricing.
Also, we no longer ship calibration kits for rental since the return shipper must be a certified hazardous materials shipper. Rental rates are based on 25% calibration gas usage per week (based on tank pressure).
Overages will be billed in 25% increments in addition to the rental rate.
