Cunyuer Hour Meter 12–36V Quartz Sealed Mechanical Gauge — Compact 2.2in Runtime Logger

The Cunyuer 12–36V quartz hour meter is a sealed mechanical gauge that records run-time up to 99,999.9 hours for engines and equipment to help track service intervals.

Keep accurate runtime records for maintenance with a rugged, low-power hourmeter designed for small engines and mobile equipment. This compact instrument accepts 12–36V AC or DC, features quartz timing for steady accuracy, and is built to resist moisture and vibration when installed properly. It’s a straightforward way to know exactly how long a motor has operated so you can plan oil changes, belt checks, and other preventive care.

How does the Cunyuer hour meter measure engine hours?

The meter uses a quartz-based counting mechanism coupled to a mechanical display that advances with power applied. Because it runs on either AC or DC within a broad 12–36V window, it will count whenever the machine’s electrical system is live.

• Quartz timing provides consistent counting with ±0.01 accuracy.
• Counts continuously while voltage is present; stops when power is removed.
• Displays up to 99,999.9 hours on a mechanical numeric register.

Will it work with my boat, tractor, or generator?

This hourmeter is built for a wide range of small to mid-size engine applications, including marine, agricultural, powersports, and stationary generators. Verify your system provides 12–36 volts AC or DC and has a place to mount the 2.2-inch diameter gauge.

• Compatible with boats, lawn tractors, ATVs, UTVs, snowmobiles, motorcycles, go-karts, and generators.
• Accepts both AC and DC within the specified voltage band for flexible installation.
• Compact 5.8 cm face diameter fits most instrument panels and dash cutouts.

What are the durability and installation considerations?

The unit is sealed against moisture and designed for low power use, but long-term exposure to heavy rain or submersion is not advised. Install it in a protected dash or enclosure when possible, and follow wiring practices for your vehicle or machine to ensure reliable operation.

• Complete sealing and anti-vibration construction for rugged environments.
• Low current draw reduces impact on battery and electrical system.
• Recommended for sheltered mounting—avoid prolonged direct rain exposure to maximize lifespan.

How do I choose between single or multi-unit purchases?

If you maintain several machines or want a spare for rotation, buying a multi-pack can lower per-unit cost and simplify replacements. Consider one meter per engine to keep independent runtime records for each item you service.

• Single units for one-off installations or replacements.
• Two-piece sets offer a cost-effective option for fleets or multiple tools.
• Labeling each meter by vehicle or engine helps keep maintenance logs organized.

Who is this for: The Cunyuer 12–36V quartz hour meter is suited to owners and operators of small engines who want a reliable, easy-to-read runtime recorder. It’s ideal for boaters, landscapers, farmers, off-road enthusiasts, and anyone running portable generators who needs accurate service interval tracking without complicated electronics. Choose this gauge if you want a simple, durable way to log engine hours and plan routine maintenance on multiple machines.
