there is only one dial and one needle, but 2 sets of numbers, like on a dial type speedometer with mph on the outer side and kph on the inside.
Thanks again
The outside # are in inches of Hg. The inner ones are k Pa. In our industry most refer to inches of mercury and with a dairy type vac. pump will run 15" to 20" but with a liquid ring most run 24" to 25".
