Suitable for

• Domestic boiler and radiator pressure monitoring
• Circulation circuit pressure checks in small commercial installations
• Routine maintenance and inspection of heating systems

Key specifications

• Dial diameter: 63 mm
• Measuring range: 0–2.5 bar
• Connection: 1/4" threaded
• Accuracy: Class 2.5
• Application: Heating system pressure measurement

How to use

Install the gauge into a compatible 1/4" threaded port on the boiler, radiator or circulation circuit following the system manufacturer's instructions. Position the dial so it is easily readable during normal operation. After installation, bring the system to operating temperature and observe the pressure reading to verify it falls within the expected range for the specific heating installation. Periodically inspect the gauge for physical damage or leakage and replace it if the glass, case or connection shows signs of wear.

Usage recommendations

Use the Afriso 63511 RF 63 AX for regular pressure monitoring of domestic and light commercial heating systems. Avoid exposing the gauge to pressures above the specified 0–2.5 bar range and protect it from mechanical shocks and freezing conditions to maintain measurement accuracy. For installations requiring higher precision, consider instruments with a finer accuracy class.
