YOOREAL Digital AC/DC Hour Meter 5–277V Waterproof IP68, Panel-Mount Runtime Counter with Backup Battery

YOOREAL Digital AC/DC Hour Meter is a sealed, panel-mount run-time counter that records equipment operating hours across AC and DC supplies from 5V to 277V.

This compact, snap-in hour meter combines wide-voltage compatibility with IP68 waterproofing and an onboard battery to preserve accumulated time when power is removed. It’s built for machines, engines, pumps and equipment that need scheduled maintenance tracking or warranty validation, and it fits standard 37.5 x 24.5 mm panel cutouts for quick installation.

How does this hour meter work with different electrical systems?

The YOOREAL hour meter accepts both AC and DC inputs across a broad range, so a single unit can monitor 12V vehicle systems, 24V industrial equipment or mains-level supplies up to 277V. It senses supply presence and tallies run time automatically while powered.

• Operating voltage: 5V–277V AC/DC, compatible with 12V, 24V, 48V, 110V, 220V and more.
• Auto-detects AC or DC without polarity-sensitive wiring for easier hookup.
• Displays cumulative hours with two resolution ranges for accuracy.

What accuracy and display resolution does the meter offer?

Readout resolution adapts to the total hours counted: tenths of an hour when under 10,000 hours, then whole-hour increments thereafter. The counter shows values from 0 up to 99,999 hours so it covers both short-interval tracking and long-term service life monitoring.

• 0–9,999.9 hours shown with 0.1-hour precision for precise maintenance intervals.
• 10,000–99,999 hours shown with 1-hour precision for long-life equipment.
• Large numeric display protected by a PC cover for readability and durability.

Is the unit durable and suitable for outdoor or harsh environments?

The meter is sealed with 100% epoxy resin and a clear polycarbonate front to resist moisture, impact and vibration. Rated IP68, it’s designed to tolerate wet conditions and routine cleaning, making it suitable for marine, agricultural and outdoor machinery.

• IP68 waterproof rating — protected against dust and long immersion in water.
• Epoxy potting prevents internal moisture and shields electronics from shock.
• Built-in CR2050 battery retains time count while power is off.

How easy is installation and what accessories are included?

Installation is straightforward thanks to a snap-in housing that fits a standard 37.5 x 24.5 mm panel cutout and non-polarized connections for faster wiring. YOOREAL supplies the meter with the expected accessories for mounting and offers two-year after-sales support for technical questions.

• Snap-in design for quick panel mounting (approx. 37.5 x 24.5 mm cutout).
• Non-distinct positive/negative poles simplify wiring in many systems.
• Includes mounting accessories and backed by 2-year customer support.

Who is this for? Technicians, fleet managers, equipment owners and OEMs who need a reliable, low-maintenance run-time recorder for a wide variety of AC and DC powered devices will benefit from this meter. It’s ideal where waterproofing, long-term tracking and simple installation are priorities — think generators, compressors, tractors, boats, HVAC units and factory machines that require scheduled upkeep or usage logging.
