Cunyuer Hour Meter 12–36V Quartz mechanical hourmeter gauge — sealed, low‑power for boats, tractors & generators

The Cunyuer quartz hour meter is a sealed, low-power mechanical gauge that records engine run time from 0 to about 99,999.9 hours for 12–36V DC/AC systems.

Designed for small engines, marine craft, utility vehicles and portable generators, this compact hourmeter delivers reliable time tracking so you can plan service intervals and monitor equipment usage. It combines a wide input-voltage window with quartz timing accuracy and a weather-resistant housing, making it a versatile choice where simple, automatic hour counting is needed.

How accurate and durable is this hour meter?

The Cunyuer hour meter uses quartz timing to keep counting accuracy close to the rated tolerance and is built into a sealed mechanical-style housing for long life. Its counting precision and a high maximum reading make it suitable for long-term maintenance schedules.

• Quartz-based timing for consistent counting accuracy.
• Rated counting range near 99,999.9 hours for long service records.
• Sealed construction to resist moisture and dust in typical outdoor use.
• Low power draw to avoid battery drain on vehicles and small engines.

Which machines and electrical systems will it work with?

This hour meter is made to accept a broad voltage range, so it fits many 12–36V DC or AC systems without additional converters. It’s commonly used on boats, tractors, ATVs, UTVs, lawn equipment, generators and other small-engine applications.

• Runs directly off 12V–36V DC or AC input — no separate power module required.
• Ideal for marine panels, motorcycle/ATV dashboards and generator control boxes.
• Works well with small engines like go-kart motors, lawn tractors and utility rigs.

What are the installation size and practical fitting considerations?

The meter is compact and made to fit common instrument panels with a circular cut-out near its 2.2-inch diameter. Its depth and sealed body let it sit into consoles or dash panels while keeping wiring protected.

• Face diameter about 5.8 cm (2.2 in) for standard panel mounting.
• Overall height roughly 7.6 cm (2.9 in), suitable for shallow dash cavities.
• Simple two- or three-wire hookup depending on system — follow polarity and grounding practices.
• Recommended to avoid prolonged direct rain exposure despite water-resistant sealing.

How should I maintain and get the most from this hourmeter?

Because the unit is designed for low maintenance, regular checks are limited to verifying the mounting, connections and that the lens stays clear. For longest life, keep it protected from continuous heavy rain and extreme vibration when possible.

• Inspect wiring and fasteners during routine service intervals.
• Use in covered or vehicle-installed locations rather than continuously exposed outdoor mounts.
• Consider the two-piece set if you need identical meters for multiple machines.
• Record hour readings on service logs to support timely oil changes and inspections.

Who is this for: The Cunyuer 12–36V hour meter is aimed at owners and operators of small-engine equipment — boaters, landscapers, ATV/UTV riders, generator owners and fleet managers — who want a straightforward, durable way to monitor accumulated run time and plan maintenance without complex electronics.
