ECA 450

Combustion Efficiency & Emissions Analyzer

Combustion &

Environmental Analyzers

Unlike any other industrial grade combustion efficiency and environmental analyzer on the market
today, the ECA 450 conducts accurate combustion and emissions tests that will help you meet
environmental regulations and ensure your equipment is burning efficiently.

Flue-Gas Sample Conditioning System

Used in conjunction with the ECA 450, the Flue-Gas Sample
Conditioning System functions to remove water vapor from
the flue-gas sample, thus preventing the formation of water
droplets inside the probe hose. If water droplet were to form,
a portion of the gas sample could be absorbed by the water,
thus resulting in lower-than-actual NO2 and SO2 readings.

Probes Available in Varying Lengths & Styles

The wireless, hand-held remote is recommended for use
of up to 300 ft. indoors with normal obstructions and up
to 1,000 ft. outdoors.

Applications

The ECA 450 is ideal for professionals concerned about combustion
efficiency, environmental compliance, or both. It enables plant
maintenance engineers and managers, industrial boiler/furnace service
technicians, energy coordinators, compliance officers, environmental
auditors and safety managers to ensure that industrial equipment is
burning efficiently while environmental regulations are being met.
