A Class 1 4.5″ Pressure Gauge 30-0-400 is a high-precision pressure gauge designed for measuring and displaying pressure levels in various applications, including industrial, firefighting, and emergency service applications.
4.5″ refers to the diameter of the gauge face.
30-0-400 refers to the pressure range of the gauge, in pounds per square inch (PSI). This means that the gauge can measure pressure levels from 30 to 400 PSI.
Class 1 pressure gauges are typically more expensive than other types of pressure gauges, but they are also more accurate and durable.
Here are some of the key features of a Class 1 4.5″ Pressure Gauge 30-0-400:
- High accuracy: ±1% of full scale range
- Large, easy-to-read dial
- Durable construction
- Variety of mounting options
- Meets or exceeds ANSI and NFPA standards
