What It Is / How It Works
This 85mm 3-in-1 tachometer gauge combines engine RPM, water temperature and oil pressure readings in one housing. It is designed for 12V or 24V systems and gives real-time engine data at a glance.
Who It's For / Use Cases
It suits car enthusiasts who want engine readings in a single gauge, boat owners who need a waterproof gauge for marine conditions, and motorcycle riders who want a compact tachometer and temperature gauge.
How to Use / Care
- Use it as a single instrument for monitoring RPM, water temperature and oil pressure on a project vehicle.
- Connect the gauge to the engine's sensors, as in a classic car restoration.
- Use it on a boat, where the IP67 rating suits wet conditions.
- Use it on a motorcycle with a 12V or 24V electrical system.
How to Choose
Check that your electrical system is 12V or 24V, since the 9 to 32VDC operating range covers both. Compare the tachometer range against your engine type, as the gauge can be set from 0-3000rpm up to 0-8000rpm. If you want RPM, water temperature and oil pressure in one view, a combined gauge saves space on the dashboard.
Frequently Asked Questions
Does this gauge work with a 12V car battery?
Yes. It operates on 9 to 32VDC, so it works with standard 12V car electrical systems.
Can I use this gauge on a boat?
Yes. The IP67 rating makes it waterproof and suitable for marine use, even in wet conditions.
Can I use this gauge on a motorcycle?
Yes, as long as your electrical system is 12V or 24V.
How accurate is the oil pressure reading?
The stepper motor drive gives precise pointer movement, reading oil pressure from 0 to 10 Bar.
What does the tachometer measure?
It measures engine RPM and can be set from 0-3000rpm up to 0-8000rpm, depending on your engine type.
