An electric hour meter is the simplest way to log operating hours on any machine that runs on AC or DC power. This compact panel‑mount device records from 0 to 999,999 hours with selectable 0.1H or 1H resolution, works on AC 86‑230V or DC 4.5‑90V, and features a resettable total counter – helping you schedule maintenance, verify warranty usage, and boost resale value.

Feature
- Resettable up to 999,999 hours: This electric hour meter lets you reset the total hours after a major service or before resale. No need to lose long‑term tracking – simply reset and continue using the same digital hour meter for new duty cycles.
- AC 86‑230V or DC 4.5‑90V input: Choose between two voltage versions of this ac/dc hour meter. Use AC 86‑230V for generators and industrial equipment, or DC 4.5‑90V for battery‑powered machines like boats and ATVs – perfect electric hour meter for boat or off‑grid gear.
- 0.1H / 1H selectable precision: Fine resolution (0.1H = 6 minutes) catches short run cycles for hour meter for air compressor duty cycles; 1H mode saves display space for long‑life industrial equipment.
- IP65 surface waterproof: Dust‑tight and protected against low‑pressure water jets, this boat hour meter survives deck washdowns, rain, and workshop dust – critical for marine, construction, and outdoor power equipment.
- LCD display 25.5x7.6mm: Large, crisp digits allow quick reading from standing position, reducing downtime when checking hour run meter on forklifts or floor machines.
Installation
NOTE: Panel cutout required: 53 x 32 mm (same as product body). Use the mounting bracket or two screws to secure the hour meter from behind.
- Push engine hour meter into a panel cutout from the front.
- Lock it in place with the included bracket or two screws – both methods hold firmly for marine or industrial use.

Applications
This industrial hour meter fits nearly any powered machine, including marine applications (outboard motors, boat electronics), vehicles (ATVs, golf carts, buggies), garden and farm equipment (mowers, trimmers, tillers, harvesters), construction machinery (compactors, rollers, concrete saws), and stationary equipment (air compressors, generators, vacuum pumps, UV sterilizers).

FAQs
Q: Can this electric hour meter be reset after a major engine overhaul?
A: Yes. This digital hour meter features a total reset function. Press and hold the reset button for 3 seconds to zero the display – perfect for tracking new service intervals or pre‑sale condition checks.
Q: What happens when the meter reaches 999,999 hours?
A: Once the maximum count is reached, the hour meter for generator or air compressor automatically rolls over to 0 and continues counting. Total runtime beyond 999,999H is not permanently stored unless you manually record the rollover event.
Q: Will the same electric hour meter work on both 110V and 220V systems?
A: Yes, if you choose the AC version (86‑230V input). That single AC version works on standard US household 110V, European 220V, and industrial 208V circuits – no need to order different AC models. For DC-powered equipment (boats, ATVs, battery systems), select the DC version (4.5‑90V) instead.
