It combines water temperature, oil pressure, and voltage monitoring in one 52mm unit. The bright red LED display makes it easy to read at a glance, even in direct sunlight or low light conditions. Built-in alarms alert you when readings go outside safe operating ranges, helping you catch potential problems before they cause serious damage.\u003c\/p\u003e\n\u003cp\u003eThis gauge is designed for a wide range of 12V and 24V vehicles, including cars, boats, trucks, and off-road vehicles. It works with an operating voltage range of 8V to 32V, giving you flexibility across different electrical systems. The 316 stainless steel construction and IP67 waterproof rating mean it can handle tough environments, from engine bays to marine dashboards, without failing due to moisture or vibration.\u003c\/p\u003e\n\u003cp\u003eThe gauge comes with a water temperature sensor that supports multiple thread sizes, including 1\/8NPT, 3\/8NPT, M14X1.5, and M16X1.5. The oil pressure sensor uses a 1\/8NPT thread. The built-in MCU provides stable performance and can match many types of sensor signals, including analog signals. If a sensor disconnects, the display shows \"OFF\" so you know immediately that something is wrong.\u003c\/p\u003e\n\u003cp\u003eAlarms are pre-set for critical conditions. The water temperature alarm triggers above 95 degrees Celsius. The oil pressure alarm triggers below 0.8 bar. For 12V systems, the voltage alarm triggers below 11.5V. For 24V systems, the voltage alarm triggers below 22V. These alarms help you stay informed without constantly watching the display.\u003c\/p\u003e\n\u003cp\u003eKey Features and Benefits\u003c\/p\u003e\u003cp\u003e- 3 in 1 design that combines water temperature, oil pressure, and voltage monitoring into one gauge, saving dashboard space and simplifying installation\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eHigh brightness red LED display that provides clear visibility in bright sunlight and low light conditions, so you can read data at a glance\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eBuilt-in alarm system that alerts you when water temperature exceeds 95 degrees Celsius, oil pressure drops below 0.8 bar, or voltage falls outside safe range, helping you prevent engine damage\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eIP67 waterproof and dustproof rating that protects the gauge from moisture, spray, and dust in engine bays and marine environments\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e316 stainless steel construction that resists corrosion from acid, base, and humidity, ensuring long-term reliability\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eImported MCU with stable performance that supports multiple sensor signal types, including 0-190 ohm, 240-33 ohm, 0-5V, 0.5-4.5V, and 4-20mA analog signals\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor disconnect alarm function that displays \"OFF\" when a sensor is disconnected, so you know immediately if there is a wiring issue\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eCompatible with 12V and 24V systems with an operating voltage range of 8V to 32V, making it suitable for cars, trucks, boats, and off-road vehicles\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWho Is This For\u003c\/p\u003e\u003cp\u003e- Car enthusiasts who want to monitor engine health with a single, easy-to-read gauge instead of multiple separate units\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eBoat owners who need a waterproof, corrosion-resistant gauge that can handle the humid and salty conditions of marine environments\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eTruck and van drivers who rely on 24V electrical systems and need a gauge that works across both 12V and 24V setups\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eDIY mechanics and custom builders who want a versatile gauge that supports multiple sensor thread sizes and signal types for different engine configurations\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eUsage Scenario\u003c\/p\u003e\u003cp\u003eMark was driving his classic pickup on a long highway trip when he noticed the oil pressure reading on his new gauge dropping below normal. The red LED display caught his eye immediately. He pulled over, checked the oil level, and found a slow leak. Because the gauge gave him an early warning, he was able to add oil and tighten the drain plug before the engine suffered any damage. He says the alarm system alone is worth the upgrade.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eUnlike basic single-function gauges that only show one reading, this 3 in 1 unit gives you water temperature, oil pressure, and voltage all in one compact 52mm housing. Many standalone gauges lack built-in alarms, forcing you to watch the needle constantly. This gauge has pre-set alarms that alert you automatically when readings go out of range. The IP67 waterproof rating and 316 stainless steel construction also make it more durable than standard plastic-housed gauges that can fail in wet or corrosive environments.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003eGauge Diameter: 52mm \/ 2.0 in\u003c\/p\u003e\n\u003cp\u003eItem Weight: 150g \/ 5.3 oz\u003c\/p\u003e\n\u003cp\u003eMaterial: 316 stainless steel and plastic\u003c\/p\u003e\n\u003cp\u003eOperating Voltage: 8V to 32V DC (compatible with 12V and 24V systems)\u003c\/p\u003e\n\u003cp\u003eOperating Current: 60mA or less\u003c\/p\u003e\n\u003cp\u003eOperating Temperature: -20 to 70 degrees Celsius\u003c\/p\u003e\n\u003cp\u003eStorage Temperature: -30 to 80 degrees Celsius\u003c\/p\u003e\n\u003cp\u003eWater Temperature Range: 0 to 120 degrees Celsius\u003c\/p\u003e\n\u003cp\u003eWater Temperature Alarm: Triggers above 95 degrees Celsius\u003c\/p\u003e\n\u003cp\u003eOil Pressure Range: 0 to 10 Bar\u003c\/p\u003e\n\u003cp\u003eOil Pressure Alarm: Triggers below 0.8 Bar\u003c\/p\u003e\n\u003cp\u003eVoltage Alarm (12V system): Triggers below 11.5V\u003c\/p\u003e\n\u003cp\u003eVoltage Alarm (24V system): Triggers below 22V\u003c\/p\u003e\n\u003cp\u003eWater Temperature Sensor Threads: 1\/8NPT, 3\/8NPT, M14X1.5, M16X1.5\u003c\/p\u003e\n\u003cp\u003eOil Pressure Sensor Thread: 1\/8NPT\u003c\/p\u003e\n\u003cp\u003eWaterproof Rating: IP67\u003c\/p\u003e\n\u003cp\u003ePackage Includes\u003c\/p\u003e\u003cp\u003e- 1 x Gauge\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e1 x Sensor\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e1 x Manual\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e1 x Cable\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWhy You Will Love It\u003c\/p\u003e\u003cp\u003eYou get three critical engine readings in one compact gauge, which simplifies your dashboard and reduces wiring work.
