FUJI FJN-501 Portable Water Pressure Recorder
The FUJI FJN-501 Portable Water Pressure Recorder is a quartz clock-based, field-ready device designed to continuously and accurately monitor water pressure. Available in two types (Type A and Type C), it enables time-based recording either by the hour or by the minute, providing flexibility for different monitoring needs.
Built with a weather-resistant ABS resin case and waterproof design, the FJN-501 is perfect for on-site inspections conducted by water utility companies, maintenance teams, and piping technicians. Its analog chart recording method makes it easy to interpret water pressure trends in various distribution systems.
