Designed for use for regulatory compliance and maintenance in industrial boiler, burner, engine, turbine, furnace, and other combustion applications, the new E850 Plus includes up to nine gas sensors and a chiller. It also comes with an optional sample conditioning unit to minimise NOX loss from condensation.

New features also include NO and NO2 sensors for true NOX measurements, a PID VOC sensor option, new display and keypad design, easier filter replacement and inspection, and expanded internal memory.
