Pressure Gauge Afriso RF 100 rad, Ø100 mm, 0–25 bar, G1/2" connection, accuracy class 2.5 (63616)

Afriso RF 100 rad pressure gauge with a 100 mm dial provides mechanical pressure indication for heating and hydronic systems. The instrument covers a measuring range of 0–25 bar and features a radial G1/2" connection suitable for panel or pipe mounting. Built to deliver robust, maintenance-free readings without electronics, this gauge is intended for continuous monitoring of system pressure in boilers, radiators and other closed circuits where reliable analog indication is required.

Advantages

The pressure gauge offers a large Ø100 mm dial for clear visibility and a radial G1/2" connection for flexible installation. Its mechanical design ensures that readings are available without power or electronic components, and the accuracy class 2.5 provides dependable performance for general service and maintenance tasks. The compact construction allows installation in tight spaces on panels or piping runs and resists typical mechanical loads encountered in heating systems.

Suitable for

• Monitoring pressure in boilers and central heating systems
• Use on radiators and hydronic circuits
• Service, inspection and routine maintenance tasks
• Panel or pipe mounting where a radial G1/2" connection is required

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–25 bar
• Connection type: radial G1/2"
• Accuracy class: 2.5
• Indication: mechanical (analog)
• Mounting: panel or pipe

How to use

Install the gauge by mounting the radial G1/2" connection to the appropriate system tapping or panel hole, ensuring proper sealing with compatible thread sealant or tape. Position the dial for easy reading and tighten the connection to recommended torque values for G1/2" fittings. The gauge provides direct mechanical readings; observe the needle position to determine system pressure. For accurate inspection, allow the system to stabilise before taking a reading and avoid rapid pressure shocks to the instrument.

Usage recommendations

Use the gauge within its 0–25 bar range and in environments appropriate for mechanical instruments. Protect the device from strong vibrations and corrosive media, and verify thread compatibility before installation. Periodic visual inspection for damage and comparison with a calibrated reference during scheduled maintenance will help ensure continued reliability.
