Extremely accurate capsule gauges designed measure pressure below inH2O. Dual scale reads to 35 OZin2. Made for work in gaseous media. The gauges have a recalibration screw to adjust the pointer if necessary.
These gauges are made for extremely low pressure situations. A one-piece capsule inside the gauge expands to register minute changes in pressure.
