SISCO waterproof tach hour meter combines portability with accuracy, featuring a speed range of 0–30,000 RPM, 0.1 RPM resolution, and 1% measuring accuracy. Powered by a DC 3V supply, the meter is designed for 2-cylinder 4-stroke engines and includes a 1-meter induction cable. The compact dimensions of 175.2 × 98.7 × 16.8 mm and lightweight 67g construction make the device ideal for field use, while the LCD display provides clear and easy-to-read measurements.
Core Functions and Performance Parameters
- Non-resettable Total Runtime Tracking: It records the total operating hours of the engine, and the accumulated total hours cannot be reset.
- Wide Timing Range: The timing range covers 0-99999H, meeting the full-lifecycle runtime statistics needs of most small engines without frequent reset or replacement.
- Clear Visual Display: Equipped with an LCD screen, the hour meter clearly shows current timing data. Dual mounting holes are also reserved for flexible installation on different devices.
- Signal-triggered RPM Display: The meter continuously detects engine ignition signals. Upon receiving valid signals, the main interface automatically displays the current engine speed without manual switching.
- Broad RPM Range: The speed measurement range reaches 0-30000 RPM, covering all working conditions such as idle speed, rated speed, and maximum speed.
- Enhanced Data Stability: The chip is optimized for engine condition monitoring, enabling accurate ignition signal capture, fast data processing, and consistent output.
- Low Power Consumption: The smart chip balances computing power and energy efficiency, resulting in ultra-low operating power.
IP68 Waterproof Performance
- IP68-rated Sealing: Waterproof tach hour meter meets the IP68 professional waterproof and dustproof standard, the highest level for industrial equipment, ensuring all-around protection against water and dust ingress.
- Precision Potting Process: The back of the waterproof hour meter is fully sealed with advanced potting technology, preventing moisture and dust from entering the core circuits, even in humid or dusty conditions.
Applications
Tach hour meter is widely applicable to gasoline engine-powered equipment across various industries, including garden machinery such as lawn mowers, chainsaws, hedge trimmers and wood chippers, agricultural machinery like rice transplanters and weeders, road construction machinery including tampers, grinders and concrete cutters, vehicles and recreational equipment such as motorcycles, golf carts, go-karts and ATVs, marine equipment like motorboats and yachts, as well as all other types of gasoline engine devices.

Q1: What is a waterproof hour meter?
A1: A Waterproof hour meter is a device used to record the total operating time of equipment while being protected against water, rain, and moisture. It is designed for use in outdoor or harsh environments where exposure to weather, dust, or splashes is common. It helps users track runtime for maintenance and servicing, ensuring machines like boats, lawn equipment, generators, and construction tools are serviced at the right intervals.
Q2:What is the waterproof rating of this hour meter?
A2: It features a professional IP68 full waterproof & dustproof grade. The sealed integrated housing effectively resists rain washing, splashing water, sea salt spray, and humid environments. It can adapt to outdoor, marine, and wet working conditions. Note: Please avoid long-term deep underwater submersion and high-pressure water flushing.
Q3: What is the difference between a tachometer and a tach hour meter?
A3: A tachometer measures the engine’s real-time speed (RPM), showing how fast the engine is running at any moment. A tach hour meter combines two functions: it measures engine RPM like a tachometer, and also records total operating hours like an hour meter. In short, a tachometer shows instant speed, while a tach hour meter shows both speed and accumulated runtime.
Tips: How does a waterproof tach hour meter work?
A Waterproof tach hour meter works by detecting signals from the engine, such as ignition pulses, electrical current, or vibration. When the engine starts running, the meter automatically begins recording operating hours. At the same time, the tach function calculates engine RPM by measuring the frequency of these signals, allowing real-time monitoring of engine speed and total runtime in one device.
