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 hours 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 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
