Minimum Requirements 1) The OP TDL instrument must be able to measure either NH3 or CH4. 2) OP CH4. TDL must be able to measure CH4.concentration at a minimum of 2 ppm-m; Sensitivity: 0.5 ppm-m; Full Scale: 8,500 ppm-m. 3) OP NH3. TDL must be able to measure NH3 concentration at a minimum of 8 ppm-m; Sensitivity: 2 ppm-m; Full Scale: 6,500 ppm-m. 4) OP TDL path length (separation path) of operation should be between 5 to 500 m. 5) OP TDL must be able to store data for months at a time. 6) OP TDL must be able to have remote diagnostics and data transmission via wireless communications 7) OP TDL must be able to compensate for pressure and temperature from internal pressure and temperature sensors. 8) OP TDL must include Onboard Firmware (no computer required for operation) 9) OP TDL must have little to no temperature drift from -40 to 50C. 10) OP TDL must have a touchscreen interface with numerical/graphical data displays, including spectral waveforms.
