Automotive instrument cluster for continuous monitoring of oil pressure, fuel level, water temperature and battery voltage that helps avoid unexpected failures. Piousunt 4-in-1 Multifunction Gauge brings four key readouts into a single 85mm unit for tidy dashboards and marine panels. Will it suit DIY restorations and mixed vehicle use?
⚡ At a Glance
- • Readouts: Oil pressure, water temperature, fuel level and voltmeter displayed on one 85mm gauge
- • Best for: DIY mechanics, classic car restorers and small boat owners needing consolidated monitoring
- • Not ideal for: Buyers who expect sensors to be supplied or who run 24V electrical systems
Four separate measurements are combined into a single 85mm instrument with seven-colour backlight. Alarm messaging flags low fuel, low oil pressure, high temperature and low voltage.
Early fault detection – thanks to configurable alarm messaging
Alarm thresholds trigger when fuel falls below 13%, coolant temperature exceeds 95°C, oil pressure drops under 0.8 Bar, or voltage falls below 11.5V. The gauge monitors incoming sensor signals and displays an alarm message when readings cross set limits.
Prompt warnings help prevent engine damage and avoid being stranded by signalling developing faults before they become serious.
Wide sender compatibility – with adjustable input ranges
Fuel sender inputs accept 0–190 ohm or 240–33 ohm configurations, oil pressure input covers 10–184 ohms, and temperature input uses the 301–22 ohm range. Signal adjustment allows matching of many common vehicle and marine senders.
One instrument supports a variety of senders, reducing the need for bespoke gauges when rebuilding dashboards or fitting to different vehicle types.
Robust, marine-ready build – with stainless bezel and IP67 protection
316 stainless steel bezel combined with curved glass contributes to mechanical strength while the unit carries an IP67 protection rating, meaning the body is sealed against dust and temporary immersion. The whole construction suits exposed dash locations.
Durable materials and waterproofing make the gauge appropriate for boats and outdoor-facing dashboards where moisture and spray are a concern.
✨ The 4 Key Reasons for Piousunt 4-in-1 Multifunction Gauge

❓ Frequently Asked Questions
Q: Are sensors included with the gauge?
A: No, sensors are not included; the listing specifies input parameter ranges for fuel, oil pressure and temperature senders so compatible sensors must be supplied separately.
Q: Is the gauge waterproof for marine use?
A: Yes, the body carries an IP67 rating and has a 316 stainless steel bezel with curved glass, designed to withstand dust and temporary immersion.
Q: What electrical system is required?
A: Designed for 12V systems with a voltage sensing range of 8–16V, the gauge is not specified for 24V vehicle systems.
🏆 Our Verdict
Best suited to DIY installers, classic car restorers and small-boat owners who need consolidated instrumentation and clear alarms. Consolidating oil pressure, fuel level, temperature and voltage into a single 85mm unit with adjustable inputs and IP67 protection is the main selling point. For anyone fitting a tidy, rugged dash display while sourcing compatible senders, the gauge represents a practical, long-term monitoring solution.
