Pressure gauge Afriso RF 100 rad, 100 mm, 0–2.5 bar, G1/2" connection, class 2.5

Afriso RF 100 rad is a dial pressure gauge with a 100 mm diameter dial and a measuring range of 0–2.5 bar. It features a G1/2" threaded connection and accuracy class 2.5, designed for reliable monitoring of system pressure in heating installations and general industrial applications. The instrument is intended for installation on radiators or heating circuits where clear, easy-to-read pressure indication is required.

Advantages

The gauge offers a large 100 mm dial for improved readability and a compact mechanical design that fits standard radiator and heating circuit connections. With accuracy class 2.5 it provides dependable indication for routine monitoring and maintenance tasks. The G1/2" connection ensures compatibility with common plumbing fittings, and the robust construction supports continuous operation in residential and commercial systems.

Suitable for

• Pressure monitoring on radiators and heating circuits
• Routine system checks in residential and commercial heating
• General industrial pressure indication where 0–2.5 bar range is required
• Replacement of compatible mechanical pressure gauges with G1/2" connection

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–2.5 bar
• Connection type: G1/2" threaded
• Accuracy class: 2.5
• Display: analog dial with pointer
• Intended installation: radiator or heating circuit mounting

How to use

Install the pressure gauge into a matching G1/2" threaded port on the radiator, boiler, manifold or heating circuit using appropriate sealing material on the threads. Ensure the gauge is mounted so the dial is visible and the pointer can move freely. After installation, pressurize the system slowly and check the reading; confirm it falls within expected operating range. For accurate readings, avoid exposing the gauge to strong vibrations or temperatures outside the manufacturer's recommended operating limits.

Usage recommendations

Periodically inspect the gauge for damage or drift and compare its indication with a calibrated reference device if precision is required. Replace the gauge if the pointer sticks, if the dial glass is cracked, or if readings are inconsistent. Use the gauge within its 0–2.5 bar range and protect it from excessive overpressure to maintain accuracy and service life.
