Heise 16" mirrored precision pressure gauge barometer
HEISE 16 inch mirrored dial precision pressure gauge.
This appears to be a precise barometer as such given the pressure range.
" 0-30 psia means pounds per square inch atmospheric. In other words, 0 psia is a pure vacuum such as outer space and 30 psia is 30 pounds per square inch above a vacuum. Atmospheric pressure is generally considered to be 14.7 psia(14.696 psia) at sea level.
Atmospheric pressure can vary day by day as per weather condition or by elevation. "
Overall diameter is about 18 inches.
Might be just what you need for your large precision pressure gauge application.
Condition looks great but we have not tested or calibrated and don't know where the dial should be pointing.
