AIMILAR mechanical hour meter DC 6–80V — sealed flush-mount 99,999.9‑hour counter

Keep precise service records for your outboard motor, generator, tractor, motocross bike or RV generator with the AIMILAR DC 6-80V Mechanical Hour Meter. Designed for flush-mount installation in confined panels, this low-power, dust- and damp-proof counter delivers reliable runtime tracking in harsh environments. With a long-life mechanical register and automatic rollover, it helps you schedule maintenance without complex wiring or frequent battery changes.

How does this hour meter work with different 6–80V DC systems?

The AIMILAR mechanical hour meter accepts a wide DC voltage range (6–80V), making it compatible with most small engines, diesel generators, and vehicle electrical systems. It begins counting when the monitored circuit receives power and stops when power is removed, providing straightforward runtime totals without electronics that can fail in damp conditions.

• Operates across 6–80V DC input for broad compatibility.
• Direct-power activation: counts only while power is present.
• Simple two-wire installation—no relay required for most setups.
• Sealed mechanical internals resistant to moisture and dust.

What are the physical dimensions and mounting requirements?

This meter is intentionally compact to fit tight instrument panels. The body measures 2.17 × 1.22 × 2.8 inches (54 × 32 × 60 mm) with a 1.77-inch (45 mm) mounting hole center, so it flush-mounts cleanly in dash cutouts. Its light 1.6-ounce weight minimizes stress on panel fastenings.

• Compact footprint: 54 × 32 × 60 mm for small panels.
• Mounting hole center: 45 mm (1.77 in) for standard dash openings.
• Flush-mount design keeps the faceplate neat and low-profile.
• Weighs about 1.6 ounces—suitable for mobile equipment.

How durable and accurate is the counter for harsh use?

The AIMILAR hour meter uses a mechanical register engineered to provide long, reliable service without sensitive electronics. Its sealed housing reduces ingress of dust and moisture, and the mechanism is designed with low power draw and automatic rollover to 99,999.9 hours for long-term tracking.

• Fully sealed case: dust-proof and damp-proof for outdoor use.
• High reading capacity: records up to 99,999.9 hours with rollover.
• Low power consumption preserves vehicle batteries and systems.
• Mechanical operation reduces vulnerability to electrical spikes.

How easy is installation and what equipment is it best for?

Installation is straightforward and designed for DIY fitment into panels on boats, tractors, generators, motorcycles and RVs. With minimal wiring and no need for a professional, owners can start tracking service intervals quickly to help maintain resale value and performance.

• Two-wire hookup—connect to switched DC power for automatic timing.
• Ideal for outboards, generators, small tractors, motocross bikes, and RVs.
• Flush-mount friendly for instrument clusters and control panels.
• Long-life counter reduces need for replacement over equipment lifetime.

Who is this for: The AIMILAR DC 6-80V Mechanical Hour Meter is made for owners and operators of small engines and mobile equipment who need a tough, no-nonsense runtime recorder. If you maintain boats, portable generators, tractors, motocross bikes, skid steers, trucks or RV powerplants and prefer a sealed, low-power mechanical solution that fits compact panels, this meter delivers dependable hour tracking without complex electronics.
