NAGANO KEIKI DG26 Differential Pressure Gauge
Made in Japan
Manufacturer: NAGANO KEIKI
Model: DG26 Differential Pressure Gauge
These differential pressure gauges are compactly designed to measure the pressure difference (differential pressure) of two points.
They can also be used to measure tank liquid level, loss of head of strainers, or combined with an office to measure the flow of a pipeline.
These differential pressure gauges with electric contacts use a microswitch for ON-OFF control.
