Features:

• Large, easy-to-read fluorescent display that is visible from wide angles.
• Battery life of over eight hours.
• Modular design lets you add sensors as your needs change.
• Built-in printer and complete data downloading to a PC capability.
• EPA-ETV test verified performance.
• Measures and displays O2 and CO in the flue gas, pressure (draft), primary air temperature, and stack temperature.
• Calculates and displays combustion efficiency, excess air, and CO2.
• Optionally measures and displays NO, NO2, SO2, HC (methane equivalent combustibles), and CO in the high range of 4,000 to 80,000 ppm).
• Optionally calculates NOx (the combination of NO and NO2), and calculates CO, SO2, and NOx individually referenced to a user defined Oxygen level of between 0 and 15%.
• Optionally displays pollution conversions for CO, NO, NO2, and SO2. Pollution conversions include parts per million, pounds of pollutant per million BTU, milligrams of pollutant per cubic meter of gas, and grams of pollutant per gigajoule.
• Stores over 1000 individual combustion and/or pressure test records, which can later be recalled for viewing or printing.
• Stored test records can be downloaded to a personal computer and stored as a text file, which can then be opened in a spreadsheet program for analysis.
• Performs datalogging.
