Series 1000 6" Dial High Precision Differential Pressure Gauges

Series 1000 6" Differential Pressure Gauge Series 1000 Gauges have capsule-type pressure elements and pressure and static connections. High differential pressure is applied to the capsule; low pressure, to the case. Available in 22 standard ranges, they combine aneroid convenience with liquid-column accuracy. They are compact for efficient panels and consoles, yet readability is excellent.
