SENCTRL 0-100 Psi Glycerin Filled Gauge
Compact yet robust, this gauge uses brass and stainless steel wetted parts suitable for measuring non-corrosive liquids and gases such as water and oil. The 304 stainless steel case provides corrosion resistance, while glycerin filling dampens pointer flutter and protects internal mechanics from vibration. Dual scale reading spans 0-100 psi and 0-700 kPa, with a stated accuracy of ±3% across the range, making it suitable for well and water pump monitoring.
SENCTRL 100 Psi Lead-Free Glycerin Filled Gauge
This version uses lead-free brass and stainless steel wetted parts, making it suitable for potable water systems and drinking-water testing. It remains compatible with water pumps, irrigation regulators, RV tanks, and more. The 2.5″ dial sits in a corrosion-resistant 304 stainless steel case, and the glycerin fill continues to minimize needle flutter while protecting the mechanism from pulsations. It measures 0-100 psi and 0-700 kPa with an accuracy of ±3% across the scale.
MEANLIN MEASURE 0-100Psi 2″ Gauge
MEANLIN’s gauge features a 2″ dial with 1/4″ NPT lower mount and a 1/2″ NPT option via an included hex bushing (3-2-3% accuracy). Designed for well pump applications, it emphasizes straightforward installation and reliable readings. The device is built for practical field use, balancing readability with a robust housing and standard connection to fit typical well systems.
AetralYB 0-100 Psi 2.5″ Gauge
With a 2.5″ dial and a glycerin-filled mechanism, this gauge emphasizes readability via a dual scale (0-100 psi / 0-700 kPa). The stainless steel and brass construction offers resilience in water and air systems. The IP67 rating ensures protection against dust and water exposure, making it suitable for outdoor installations and wet environments such as well tanks and pool-related equipment. It includes a standard 1/4″ NPT lower mount and emphasizes shock resistance through glycerin damping.
SENCTRL 100 Psi Lead-Free Gauge
This 2″ dial version focuses on potable water compatibility with lead-free brass and stainless steel wetted parts. The IP67 waterproof rating reduces condensation and fogging, keeping the display clear. It remains appropriate for water tanks, well pumps, RV regulators, and related testing scenarios, with a corrosion-resistant 304 stainless steel case protecting against harsh environments.
Measureman 2″ Well Pump Gauge
Measureman offers a 2″ dial well pump gauge with a 0-100 psi/100 kPa range and 1/4″ NPT plus a 1/2″ NPT adapter option. The 3-2-3% accuracy and center back mount provide flexible installation for testing and monitoring water pressure in well systems. This gauge is designed for straightforward field use with clear scale readability and robust mounting options.
Buying Guide: Key Purchase Considerations
- Pressure range and scale: Most residential well systems use 0-100 psi. Choose a gauge with dual scales (psi/kPa) for versatility and easier cross-checking with different equipment.
- Wetted parts and materials: For potable water applications, select lead-free wetted parts and a stainless steel case to ensure reliability and safety.
- Glycerin filling: Glycerin dampening reduces needle flutter and protects internals from pulsation, vibrations, and shock, improving readability and longevity in pump environments.
- Mounting and connections: Common connections are 1/4″ NPT lower mount or center/back mount. Ensure the thread type and size match your system fittings or include adaptors if needed.
- Protection rating: IP67 or higher ratings help resist dust and moisture, beneficial for outdoor or damp installations.
- Readability: A larger dial (2″ or 2.5″) improves visibility. Look for high-contrast markings and a bold needle for quick readings.
- Maintenance and service life: Stainless steel housings and brass or stainless wetted parts typically offer longer service life in water and air systems.
- Compatibility with fluids: Most gauges are designed for non-corrosive liquids and gases; verify compatibility with your specific fluid (e.g., potable water, irrigation water, or air).
When selecting a gauge, balance durability, readability, and compatibility with your well system. For drinking-water applications, prioritize lead-free wetted parts and a waterproof enclosure. For outdoor or vibration-prone installations, glycerin-filled gauges offer enhanced stability and longevity. Consider standardizing on a single connection size (1/4″ NPT) where possible to simplify installation across multiple pumps and regulators.
