Low NOx emissions monitor and combustion gas analyzer

The hand-held Green-Line 4000 is a rugged, accurate gas analyzer that is ideal for low NOx applications (0.1 ppm resolution) and combustion gas emissions monitoring. Features include: up to four gas sensors; low NOx sensor (0 to 500 ppm range with 0.1 ppm resolution); true NOx (NO+NO2) capability; CO sensor dilution with auto-ranging up to 100,000 ppm; efficiency, excess air, and CO2 calculations; draft and differential pressure measurements; a built-in impact printer; internal data memory, and a PC software package for data storage and unit configuration with USB cable.
