Overview
The Dixon Boss GC605 is a standard dry pressure gauge engineered for long-term reliability in industrial fluid transfer applications. With a 0–30 PSI measurement range and center back mount design, the GC605 delivers accurate pressure monitoring in pneumatic systems, hydraulic lines, compressors, pumps, and machine tool installations. Its corrosion-resistant ABS plastic case and bronze safety bourdon tube construction make it ideal for non-corrosive and moderately harsh environments.
Key Features
- Pressure Range: 0–30 PSI with 5 PSI major graduations and 0.5 PSI minor increments for precise readings
- Accuracy: ASME B40.1 Grade B (±3–2–3% accuracy) ensures reliable measurement across the operating range
- PowerFlex™ Movement: Polyester segment design resists shock, vibration, and pulsation common in industrial duty cycles
- Durable Construction: ABS plastic case with corrosion-resistant finish, polycarbonate window, and black aluminum pointer
- Bronze Bourdon Tube: C-shaped safety tube rated for low-pressure applications (600 PSI and below)
- Temperature Range: Operates reliably from –40°F to +150°F (–40°C to +66°C)
