1131 Differential Pressure Gauge
Brand: Ashcroft IncDoes not ship to OH, United States
The Ashcroft® 1131 gauges are a very economical option for measuring differential pressure and where no media migration is permissible.
Uses a rolling diaphragm design and can be utilized with compatible fluids and gases at high static pressures.
Features- Stainless steel case
- High static pressure capability (up to 3,000 psi)
- Superior magnets for smoother pointer motion
- Reed switches (optional) for direct system control
