Power 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 hrs of operation
Pumps & Probe 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 4000 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.
Size 13.5” H x 18.5” W x 9” D
Weight 25 lbs. (11.34 kg)
Warranty 1 year, extended warranty available
* Optional
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.
The maximum operating temperature for probes included in 24-7221, 24-7224, 24-7223,
24-3024 and 24-3025 is 1472°F (800°C). The maximum operating temperature for high
temperature probes 24-3035, 24-3036 and 24-3037 is 2000°F (1093°C).
