MEASUREMAN Water Pressure Gauge
The MEASUREMAN Water Pressure Gauge manages 0-200 PSI with a 2-1/2″ dial and a durable 3/4″ brass hose thread. It emphasizes accuracy for outdoor faucets, irrigation, and water systems. The brass construction supports long-term reliability in high-pressure environments, with readings designed for straightforward monitoring of pressure in various setups.
MEASUREMAN Dual Measurement Assembly
This dual-function tester measures both pressure (0-160 PSI) and flow (0-13 GPM) simultaneously. Built around a 2-1/2” dial and a rugged 3/4” NPT brass gate valve, it provides a compact solution for diagnosing sprinkler systems, home plumbing lines, and fluid flow with confidence. The dual readings help identify restrictions or pressure drops at a glance.
MEASUREMAN Brass Flow, Temperature & Pressure
This tester blends temperature, pressure, and flow with dual interfaces: a 3/4″ female hose connection inlet and a 3/4″ push-to-connect fitting. The stainless steel gauge features a 1/4″ NPT radial port, while the 2.5″ dial for pressure (0-160 PSI) and a temperature gauge (30-250 ℉) offer clear readings. The brass construction ensures durability and corrosion resistance for varied water systems.
Watflow Water Flow Gauge, Temperature & Pressure
Watflow’s 0-160 PSI gauge provides both flow (0-13 GPM) and temperature readings with a 2-1/2″ dial. Designed for sprinkler systems and general water testing, the tester emphasizes compatibility with U.S. water sources via a 3/4″ NPT gate valve and 3/4″ hose male connection. It helps users correlate pressure and flow during system design or troubleshooting.
Flow Doctor Glycerin Filled Kit
The Flow Doctor kit is a comprehensive 6-part set featuring a glycerin-filled gauge, 0-200 PSI range, and a standard 3/4″ GHT with five adapters for wide compatibility. The glycerin fill reduces pulsation for steadier readings, making it suitable for irrigation, sprinkler systems, and testing at multiple locations indoors and outdoors. Quick-connect adapters extend its versatility across different fixtures and hoses.
Buying Guide
Key purchase considerations help match a gauge to your needs:
- Pressure and flow range: Select a model covering your typical system range (PSI and GPM). Higher ranges are better for larger irrigation or municipal lines, while lower ranges can offer finer resolution for home plumbing.
- Dial size and readability: A 2-1/2″ dial is common and easy to read; ensure the scale markings are clear and color-coded for quick interpretation.
- Connections and compatibility: Check thread types (NPT, GHT, push-to-connect) to ensure compatibility with hoses, fittings, and valves in your setup.
- Material durability: Brass gates and housings resist corrosion and pressure, improving longevity in outdoor or high-flow environments.
- Dual or multiple measurements: If you need both pressure and flow (and possibly temperature), dual-dial or multi-parameter testers save time and simplify diagnostics.
- Glycerin fill vs dry gauges: Glycerin-filled gauges resist flutter and provide stable readings; however, they can be heavier and slightly slower to respond.
- Portability and installation ease: Look for quick-connect adapters or versatile fittings that reduce the need for additional tools during testing.
- Price-to-value balance: For routine checks, a reliable mid-range model may suffice; for professional diagnostics, prioritize build quality and long-term accuracy.
When selecting a pressure and flow gauge, align the tool’s capabilities with your typical use cases—outdoor irrigation, home plumbing, or workshop pneumatic systems—and consider whether you need temperature readouts or dual readings for rapid diagnostics.
