Hands Free Solutions
Strong magnetic hanger holds the
meter in place while the threaded
barrel-lock stabilizes the barrel without
damaging the ue. And the internal
pump means no more hand pumping.
Field-replaceable Sensor
Because the oxygen sensor is eld
replaceable, there is no need to send the
SOX3 in for time consuming calibration. The
display shows when it’s time for a new O
2
sensor.
Custom Fuels
Just set your SOX3 to
Custom, enter the %CO
2
max of any fuel, then
measure normally. This
screen was taken from a
wood pellet burner.
