1143 Differential Pressure Gauge
The Ashcroft® 1143 gauges are a very economical option for measuring very small differential pressure and where no media migration is permissible. Uses a convoluted diaphragm design and can be utilized with compatible fluids or gases with ranges as low as 1 in. H2O (25 mw) and where temperature fluctuations may cause readability concerns due to condensation.
Key Features:
- Glass filled nylon case
- Easily removable window for wipe-down
- Direct mount or panel mount as standard
- High static pressure capability of 500 psi
- Superior magnets for smoother pointer motion
- Reed switches (optional) for direct system control
