1133 Differential Pressure Gauge

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.

Key Features:

• High static pressure capability ( 500 psi)
• Reed switches (optional) for direct system control
• Superior magnets for smoother pointer motion

Specifications:

• 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
• Leak Detection
• Flow Measurement
• Clean Room Positive Pressure (low dp)
