ECA 450 Combustion Analyser
Datasheet
The ECA 450 is ideal for professionals concerned about improving
overall combustion efficiency, reduce fuel costs, and determine
emissions compliance.
It enables plant maintenance engineers, industrial boiler/furnace
service technicians, environmental auditors and safety managers
ensure that industrial equipment is burning efficiently while
environmental regulations are being met.
Unlike any other industrial grade combustion efficiency and
environmental analyser on the market today, the new ECA 450
from Bacharach conducts accurate combustion and emissions tests
that will help you meet environmental regulations and ensure your
equipment is burning efficiently.
The ECA takes continuous samplings of furnaces, boilers and
other industrial combustion equipment for up to eight hours
and generates precise, reliable combustion and environmental
measurements and calculations. And it generates this complex data
easily — even at selected intervals — enabling plants to make more
accurate equipment adjustments and better assess pollution levels.
Features
Applications:
• Furnaces
• Boilers
• Combustion Applications
Features and Benefits:
• 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
Measures:
• Built-in printer and complete data downloading to a PC capability
• Oxygen
• EPA-ETV test verified performance
• Carbon Monoxide
• Calculates and displays combustion efficiency, excess air, and CO2
• Nitric Oxide
• Optionally measures and displays NO, NO2, SO2, HC (methane
• Nitrogen Dioxide
equivalent combustibles), and CO in the high range of 4,000 to
• Sulphur Dioxide
80,000 ppm)
• Combustibles
• Optionally calculates NOx (the combination of NO and NO2),
• Temperature & Draft
and calculates CO, SO2, and NOx individually referenced to a user
• It also calculates combustion efficiency, excess air, carbon dioxide, defined Oxygen level of between 0 and 15%
NOx (Nitrogen Oxides) and pollution units
• 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
• Performs datalogging

Universal AC adapter and an internal battery pack. Adapter will accept input voltages from
100 to 240V. Fully charged battery pack provides a minimum of 8 hours of operation
Two pumps are included. The first pump supplies gas sample to the sensors. The second
pump supplies fresh air to purge the low-range CO sensor when CO levels exceed 400 ppm.
Probe includes a standard probe and hose assembly equipped with a water trap, particulate
filter, probe stop, 15 feet of hose, and 12-inch probe tube
