MEASUREMAN Natural Gas Or LP Gas Manifold Test Kit
The MEASUREMAN kit is designed for measuring low pressure across appliance manifolds in natural gas or LP gas applications. It features a 2.5″ dial, 40″ rubber hose, and a 1/8″ NPT brass fitting. The unit is protected in a molded plastic box for field use. Pressure range spans 0-35 inches of water column (W.C.), with typical natural gas readings around 2.5–4′ W.C. and LP gas readings around 10–12″ W.C. The kit is suitable for diagnosing manifold pressure with a compact, portable package.
MEANLIN MEASURE 0-35” WC Manifold Gas Pressure Test Kit
This manifold gas pressure tester is built around a 2-1/4″ dial face and a 40-inch extended hose. It includes 1/8″ NPT fittings with barbed connections and a hex bushing to adapt to multiple gas system configurations. The quick-connect and multiple adapters enable solid, flexible connections to various pipelines, making it suitable for different installation environments and service tasks where accurate low-pressure readings are essential.
PT520 Manometer Gas Pressure Tester
The PT520 is a digital manometer with dual input ports, capable of measuring differential gas pressure. It covers a broad range from -100 to 200 kPa (-14.5 to 29.01 psi) with an accuracy of about ±0.25% FSO. It includes 10 selectable units and various adapters to fit different pipe diameters. Features like data storage, data hold, and automatic barometric pressure calibration improve field usability. This device is well-suited for more complex HVAC diagnostics and when precise digital readings are needed.
UHARBOUR Manometer Gas Pressure Tester
The UHARBOUR tester focuses on accurate gas pressure testing with a 0-35″ W.C. range. It uses a 1/8″ NPT fitting with a barbed connection and a 40″ hose for reach. The design emphasizes a straightforward setup for measuring pressure in various gas systems, with practical flexibility for access to tight or hard-to-reach spaces while maintaining reliable connection integrity.
Leaton Manometer, Dual-Port Digital Gas Pressure Tester
The Leaton digital manometer offers dual-port operation for differential pressure measurements, which is valuable for complex gas or ventilation tests. It features a large LCD with backlight, data logging, and multiple measurement units. The device provides repeatability around ±0.2% (typical ±0.5% FSO) and ranges up to ±20.68 kPa / ±2.999 psi. It is suitable for gas line troubleshooting, air handling tests, and laboratories requiring digital readouts and memory capability.
Buying Guide: Key Considerations For Choosing A Natural Gas Pressure Tester
- Pressure range and type: Determine whether you need low-pressure (inches of water) meters for manifold testing or higher ranges for broader gas systems. Dial gauges are simple and robust; digital models offer data storage and unit flexibility.
- Connection options: Ensure fittings match your system (1/8″ NPT, 3/4″ FNPT, or other adapters). A barbed connection can help with leak-tight seals on flexible hoses.
- Hose length and reach: Longer hoses (40″) help reach hard-to-access manifolds but may affect handling. Check compatibility with your installation space.
- Accuracy and resolution: For critical diagnostics, prioritize devices with higher accuracy and clear LCD/backlit displays. Digital units provide precise readings and data history.
- Durability and workflow: Hardened casings, molded carrying boxes, and quick-connect fittings improve on-site reliability and ease of use.
- Ease of use: Consider whether you prefer analog gauges for straightforward readings or digital units with data logging and multiple measurement units for versatility.
- Safety and standards: Use testers designed for gas environments and ensure proper certification and safe-handling practices during testing.
- Compatibility with natural gas vs LP gas: Some kits are optimized for natural gas, others for LP gas. Confirm pressure ranges and fittings align with your typical fuel type.
- Maintenance and support: Look for brands offering spare parts, adapters, and clear guidance for calibration and maintenance.
