Pressure Gauge Afriso RF 100 Ø100 mm 0–6 bar 1/2" Class 1.6 (63613)

The Afriso RF 100 pressure gauge with a 100 mm dial and a measuring range of 0–6 bar is a mechanical instrument designed to monitor static and dynamic pressure in heating and hydronic systems. It features a 1/2" connection and accuracy class 1.6, providing dependable readings for residential and light commercial installations. The gauge is suitable for direct mounting on boilers, pumps and manifold assemblies to help identify pressure drops, leaks or system faults.

Advantages

This pressure gauge combines a large 100 mm dial with clear graduations for improved readability. The 0–6 bar range covers typical operating pressures of domestic boilers and circulation systems. The 1/2" threaded connection allows straightforward installation on standard fittings, while the mechanical design offers a maintenance-free operation without the need for power. Class 1.6 accuracy ensures measurements remain within acceptable tolerance for monitoring and troubleshooting tasks.

Suitable for

• Monitoring pressure in residential heating systems
• Pressure checks on circulation pumps and manifolds
• Installation on boilers and hot-water systems
• Leak detection and routine system diagnostics

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–6 bar
• Connection size: 1/2" (threaded)
• Accuracy class: 1.6
• Type: Mechanical Bourdon tube pressure gauge

How to use

Mount the gauge on a compatible 1/2" threaded port on the boiler, pump or manifold. Ensure the connection is sealed with an appropriate thread sealant or tape to prevent leaks. Position the gauge so the dial is clearly visible for routine checks. Read the pressure value from the pointer against the graduated dial while the system is at its normal operating condition. If readings fall outside expected ranges, follow system troubleshooting procedures, including checking valves, pumps and pressure regulators.

Usage recommendations

For accurate and long-term performance, avoid exposing the gauge to excessive vibration or pulsation; if such conditions are present, consider adding a snubber or siphon. Regular visual inspections and periodic comparison with a calibrated reference gauge will help maintain reliable monitoring. Use the gauge within its specified temperature and pressure limits and replace it if the pointer sticks or accuracy appears degraded.
