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.
