- Certificates & Approvals
The Ashcroft® 1133 differential pressure gauge is an economical means for measuring very low pressure with high static between two independent pressure sources. Uses a convoluted diaphragm to sense low inches of water differential pressure without migration of media between the low and high pressure sides.
- High static pressure capability (500 psi)
- Superior magnets for smoother pointer motion
- Reed switches (optional) for direct system control
- Accuracy: ±2% (ascending pressure)
- Pressure Ranges: 0-1" IWD thru 0-25" IWD
- Dial size: 3 1/2", 4", 4 1/2" and 6"
- Case: stainless steel
- Body: aluminum or stainless steel
- Wetted Material: body material, Teflon®, ceramic and various O-ring materials
The 1133 differential gauge is ideal where safe and reliable pressure measurement is essential:
- Filtration Monitoring
- Flow Measurement
- Leak Detection
- Clean Room Positive Pressure (low dp)
