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)
Superior magnets for smoother pointer motion
Reed switches (optional) for direct system control
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:
