PORTABLE GAS MONITOR
First Claim
1. A handheld portable monitor designed for periodic well field testing to enable a user to test a plurality of different landfill wells one at a time and for measuring one or more properties of fluid flowing in each of said tested 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 to be measured 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.
