Pressure Gauge Afriso RF 100, Ø100 mm, 0–4 bar, 1/2" connection, class 1.6

Afriso RF 100 pressure gauge, Ø100 mm with a 0–4 bar scale and 1/2" threaded connection, is designed for monitoring pressure in heating and hydronic systems. The 100 mm dial provides clear, easy-to-read indications and the accuracy class 1.6 delivers dependable measurements for boilers, central heating circuits and circulation loops. The robust housing and compact design allow installation on panels, walls or piping assemblies in technical rooms, plant rooms and service cabinets where continuous visual pressure control is required.

Advantages

The Afriso RF 100 offers reliable pressure indication with an accuracy class of 1.6, ensuring readings suitable for commissioning and routine inspection of heating systems. Its Ø100 mm dial enhances readability at a distance, while the standardized 1/2" threaded connection simplifies retrofit and replacement work. The instrument’s mechanical construction requires no external power and tolerates typical ambient conditions found in boiler rooms and service areas.

Suitable for

• Monitoring pressure in boilers and central heating circuits
• Hydronic systems and circulation loops
• Panel or wall mounting in technical rooms and service cabinets
• Replacement of existing inline pressure gauges with 1/2" connection

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–4 bar
• Connection: 1/2" threaded
• Accuracy: class 1.6
• Mounting: inline / panel or wall with 1/2" connection
• Display: analogue pointer on graduated dial

How to use

Install the gauge by screwing the 1/2" threaded connection into the appropriate female port on the boiler, pump housing or piping branch. Ensure connections are clean and use appropriate sealing (for example PTFE tape) if required by the installation practice. Position the dial where it is visible for routine checks and avoid locations with excessive vibration. Read pressure from the analogue pointer relative to the calibrated 0–4 bar scale; perform periodic visual checks and verify against a reference instrument during maintenance intervals.

Usage recommendations

To maintain measurement reliability, protect the gauge from freezing conditions and aggressive media, and perform regular inspections for mechanical damage or leaks. When replacing an existing instrument, match the 1/2" connection and the 0–4 bar range to ensure compatibility with system design and safety settings.
