Series 276H300 Hose Connection Gauges are used to test water supply pressures within a distribution system. This gauge will accurately show your home's water pressure. Its red indicator hand holds at the highest reading registered for detection of thermal expansion pressure surges. It features a black enamel steel case, Kostil Polymer window, 3/4 in. H.T. hose connection, and copper alloy Bourdon tube sensing element. Accuracy is ASME, Type B. Available in 0 to 300psi (21 bar) pressure rating scale.
Features: Black enamel steel case Kostil polymer window Copper alloy Bourdon sensing element Tin alloy welding 3⁄4" (20 mm) H.T. hose connection ASME Type "B" accuracy
Specifications: Approvals: Certified by The Northern Certification Society of Italy (Det Norske Verita Italia S.r.l.) Standards: ISO 9002 quality standard ASME B40.100 Working Temperature: 40°F to 140°F (4°C to 60°C
Operation: Connect this tester to a hose bib on the outside of your home. Turn on the water, let sit for 12 to 24 hours. (optional you can take hourly measurements to determine water pressure throughout the day) Return and read the red dial, showing "peak" overnight pressure, which can greatly exceed readings during the day. This will indicate your highest water pressure within the time frame you left the gauge connected.
