This model emphasizes reliability and long-term stability under frequent testing and operation.
MEASUREMAN 3.5″ Fire System Kit Gauge
This kit combines a 3.5″ 0-300 psi gauge with essential stainless steel fittings for a quick, professional installation. The 304 stainless steel case provides corrosion and shock resistance, making it suitable for harsh fire system environments. Included fittings include a 3-Way valve and NPT adapters, reducing field assembly time and ensuring reliable performance.
GOATACURA 0-300 psi Gauge
GOATACURA offers an all-brass structure designed for corrosion resistance and durability in wet or chemical environments. This 4″ dial gauge uses a lower mount and covers 0-300 psi, making it suitable for broader visibility in control rooms. Its robust construction aims to provide dependable performance in fire protection service over extended periods.
Buying Guide
Key purchase considerations help ensure the right gauge for your fire protection system:
- Measurement type: Decide between single-scale versus dual-scale gauges. Dual-scale can simplify quick interpretation when both psi and kPa readings are needed, while single-scale gauges may be easier to read in practice.
- Media compatibility: Choose water-only gauges for typical sprinkler water systems or air/water gauges for mixed media environments as required by your installation.
- Dial size and readability: Larger dials (3.5″–4″) improve visibility from control rooms. Consider the placement and lighting in the reading area.
- Connection and mounting: Most fire gauges use a 1/4″ NPT lower/mount connection. Ensure compatibility with your piping layout and consider whether a bottom-mount or radial mounting best fits your setup.
- Durability: Look for stainless steel or brass casings and protective polycarbonate lenses. In harsh environments, corrosion resistance and shock resistance extend gauge life.
- Certifications and suitability: Verify the gauge is designed for fire protection systems and meets relevant standards to ensure reliable performance during inspections and alarms.
- Installation kit vs. standalone gauge: Some products include fittings or valves, reducing installation time, while others are standalone gauges requiring separate components.
- Maintenance and longevity: Consider gauges with proven long-term stability in vigorous environments. Periodic calibration and inspection routines should be part of your maintenance plan.
