Ashcroft 1005P 300 PSI Pressure Gauge is a UL-listed and FM-approved 3 1/2" (88.9 mm) gauge designed to deliver accurate pressure readings from wet-pipe fire sprinkler system components and other water-based systems. Ashcroft's PowerFlex design separates the bourdon tube and the linkwire tube to keep stress, shocks, and vibration from travelling through the thread connection to precision parts, extending product life and accuracy.
Each Ashcroft 1005P 250 PSI Air Pressure Gauge has a 1/4" (6.35 mm) male National Pipe Thread (NPT) pressure connection that threads quickly to fire sprinkler system trim for air pressure measurements between 0 and 250 PSI. This 3 1/2" Grade-B gauge is accurate to +/-3/2/3% of span and uses a "zero zone" rather than a conventional dial post to guarantee that the the gauge reads zero only at 0 PSI, providing an immediate indication of when a gauge is out of calibration.
For $40 more, this 3 1/2" (88.9 mm) Ashcroft 1005P 250 PSI Air Pressure Gauge arrives tested and certified using the National Institute of Standards and Technology (NIST) process to meet the exacting standards of accuracy demanded by clients in the U.S. Navy, U.S. Army, aviation industry and elsewhere.Technical Documents
