Intermatic FWZ72-120U Meter

The Intermatic FWZ72-120U is a professional-grade 120V Round Flush Mount Hour Meter designed for precise equipment run-time monitoring in industrial and HVACR environments. This analog hour meter features a non-resettable 7-digit display, capable of tracking up to 99,999.99 hours, which is critical for maintaining accurate service logs and preventive maintenance schedules. Engineered with a synchronous mechanical movement, the unit operates on a standard 120VAC 60Hz frequency without the need for batteries or digital memory, ensuring data integrity even during a power loss. The 2.83-inch round bezel is designed for a secure 3-hole flush mount, fitting standard 1.75-inch panel openings. Its IP54-rated housing (when used with a gasket) provides essential protection against dust and moisture, making it a reliable choice for monitoring pumps, compressors, and control panels. With a robust operating temperature range of -40°F to 160°F, this electromechanical hour meter is built to withstand the demanding conditions of commercial mechanical rooms and outdoor enclosures.

Key Benefits for Technicians

• Maintenance Accuracy: The non-resettable display ensures tamper-proof tracking of cumulative run-time for strictly regulated maintenance intervals.
• Simplified Installation: Features a flush-mount design with combination 1/4-inch spade and screw clamp terminals for flexible wiring in tight control panels.
• High Visibility: High-contrast 0.16-inch white numerals on a black background, with yellow indicators for tenths and hundredths, allow for quick visual inspections.
• Extreme Durability: The IP54 environmental rating and wide thermal operating range ensure consistent performance in high-heat or sub-zero industrial applications.
• Energy Efficient: Extremely low power consumption of only 1 VA, minimizing the electrical load on the monitored circuit.
