## Summary description

Industrial heating pressure gauge Afriso RF 100 rad with 100 mm dial, measuring range −1 to 0 bar and G1/2" threaded connection. Designed for monitoring vacuum and negative pressures in heating systems and boilers. Bourdon-type instrument with accuracy class 2.5, suitable for panel or pipe mounting where reliable low-pressure indication is required.

## Long description

Afriso RF 100 rad pressure gauge with a 100 mm diameter dial is engineered for monitoring vacuum and negative pressure in heating systems and boilers. The instrument measures in the range −1 to 0 bar and features a G1/2" threaded connection suitable for direct pipe or panel mounting. The gauge uses a Bourdon-type sensing element and is manufactured to accuracy class 2.5, providing reliable indication of low pressures where simple, robust measurement is required.
Advantages
The gauge offers a clear, large 100 mm dial for easy reading and a compact G1/2" connection for standard system interfaces. Its Bourdon mechanism is a proven mechanical solution for long-term, maintenance‑light operation in heating applications. The −1 to 0 bar range is specifically tailored to detect vacuum and negative pressures in boilers and circulation systems, helping to identify leaks, pump cavitation or incorrect system filling. Accuracy class 2.5 balances cost and functionality for routine monitoring tasks.
Suitable for
Monitoring vacuum and negative pressure in heating systems
Pressure checks on boilers and hot-water circuits
Panel or pipe mounting where a compact, visible gauge is required
Maintenance checks to detect leaks or underpressure conditions
Key specifications
Dial diameter: 100 mm
Measuring range: −1 to 0 bar (vacuum/negative pressure)
Accuracy class: 2.5
Connection type: threaded G1/2" (for pipe or panel installation)
Sensing element: Bourdon-type mechanical element
Mounting options: panel mounting or direct pipe connection
How to use
Select an appropriate mounting point on the heating system or boiler where the gauge will be visible and protected from mechanical damage. Ensure the G1/2" threaded port is clean and apply suitable thread sealant if required by the system practice. Install the gauge hand-tight and then secure with a wrench to the recommended torque for G1/2" fittings; avoid over-tightening. With the system at rest, observe the dial to confirm the gauge indicates within the expected negative pressure range. Periodically check the gauge for mechanical damage, dirt on the dial window, and correct indication during system operation.
Использование и рекомендации
For reliable readings, avoid exposing the instrument to strong vibrations, corrosive media or temperatures outside the manufacturer's specified operating range. If the system contains condensate or aggressive fluids, consider installing a suitable isolating element or glycerine-filled variant where compatible.
