Maintenance schedules for pumps, compressors, generators and HVAC units run on hours, not calendar dates. The Intermatic UWZ48E-120U is a flush-mount AC hour meter for 120 V, 60 Hz that counts up to 99,999.99 hours on a non-resettable display.

Pro tip from the counter
Connect the meter in parallel with the load or the starter coil, on the switched side, so it only counts real run time. Tapping it across the always-live supply turns it into a clock that logs every hour the panel is energized and makes the service intervals meaningless.
Best for: pump and compressor panels, standby generators, HVAC and refrigeration equipment, rental equipment tracking, OEM control panels
