PORTABLE GAS MONITOR
First Claim
1. A handheld portable monitor for periodic well field testing of a plurality of different landfill wells and for measuring one or more properties of fluid flowing in the landfill wells, said handheld portable monitor including a plurality of connectors that enable at least a portion of said handheld portable monitor to be removably connected to the landfill well, said handheld portable monitor including a sensor arrangement to obtain and measure one or more properties of a fluid flowing in the landfill well, said handheld portable monitor including a heating system to heat one or more components of said sensor arrangement of said handheld portable monitor, said properties of said fluid flowing in the landfill well including a plurality of properties selected from the group consisting of well pressure, well temperature, LEL, UEL, well fluid composition, and composition ratio, said heating system including a microprocessor, a thermocouple and a heating element, said microprocessor activating said heating element when said microprocessor obtains information from said thermocouple that a temperature detected by said thermocouple is at or below a predefined low level temperature.

10. A method of monitoring a plurality of landfill wells comprising:
-
a. providing a handheld portable monitor for periodic well field testing of landfill wells, said handheld portable monitor used to measure one or more properties of fluid flowing in a landfill well, said properties of said fluid flowing in the landfill well including a plurality of properties selected from the group consisting of well pressure, well temperature, LEL, UEL, well fluid composition, and composition ratio, said handheld portable monitor including a handheld portable control unit and a portable measuring unit, said handheld portable control unit and said portable measuring unit each having separate housings, said portable measuring unit including a heating system, said handheld portable control unit is designed to monitor and control at least one function of said portable measuring unit, said portable measuring unit including a sensor arrangement that includes a plurality of pressure measurement components and a plurality of chemical analyzer, said heating system designed to inhibit or prevent a temperature on or about one or more components of said sensor arrangement of said portable measuring unit from falling below a predefined lower temperature while said one or more components are measuring one or more properties of said gas flowing though said landfill well; b. removably connecting said portable measuring unit to a plurality of ports on a first landfill well, said handheld portable control unit not connected to said first landfill well; c. monitoring and controlling at least one function of said portable measuring unit from a remote location by said handheld portable control unit; d. measuring a plurality of properties of said fluid flowing in said first landfill well by said plurality of pressure measurement components and said plurality of chemical analyzers in said portable measuring unit, said step of measuring being no more than about 60 minutes; e. disconnecting and removing said portable measuring unit from said first landfill well after said measuring of said first landfill well is completed; f. transporting said portable handheld portable monitor to a second landfill well; and
,g. repeat steps b-e for said second landfill well. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
