6-in-1 multifunction gauge with alarm design This instrument combines GPS Speedometer, Tachometer, Voltmeter, Fuel Level, Water Temp, and Oil Pressure in one compact unit. It helps you monitor multiple critical data points for your boat with a single gauge, reducing panel clutter and providing timely alerts when readings require attention. Key benefits - All-in-one display: monitor speed, engine RPM, battery voltage, fuel level, water temperature, and oil pressure from a single gauge. - Built-in alarm: designed to alert you to abnormal readings to help prevent engine damage or running out of fuel. - Space saving and simple to use: integrates six measurements into one TFT screen with straightforward operation. Unit switching and sensor compatibility - Use the unit button to switch between speed units (MPH, km/h, knot), water temperature (F or C), and pressure (psi or bar). - Sensor compatibility: enter parameter selection mode by pressing the button first, then power on to choose 0190ohm (European) or 24033ohm (American) level sensors. - Flexible measurement setup ensures you can match local sensor configurations for reliable readings. Display and data specifications - GPS Speedometer: 0600 (km/h, mph, knots available) - Tachometer: 09999RPM - Voltmeter: 932V - Fuel Level: 0 - Water Temp: 40120C/100250F - Oil Pressure: 010 BAR/0145 PSI - The gauge uses a TFT screen for clear readability in various lighting conditions. Marine tachometer installation - Installation requires opening a hole of 85mm (3 3/8") diameter and 55mm (2 3/16") depth to fit the unit. This design facilitates a straightforward, secure installation. Protection and durability - TFT screen provides sharp display for day or night use. - IP67 waterproof and antifogging protection ensures reliable operation in wet marine environments. 2-3 practical use scenarios - Small fishing boat setup: Install this 6-in-1 gauge on a compact helm to monitor speed, RPM, battery voltage, fuel level, water temperature, and oil pressure at a glance. The built-in alarm helps alert you to engine or fuel issues while on the water. - Coastal cruising on a motorboat: Use the European or American sensor setting to match your local wiring, and switch units to mph or knots as you navigate. Quick visibility of all critical readings helps you manage engine performance during cruises. - Boat dash upgrade in harsh conditions: The TFT display combined with IP67 antifog protection provides durable readability in spray-prone or humid environments, reducing the need for multiple gauges and improving reliability. Notes - The product is designed to integrate multiple engine and vessel readings into a single, easy-to-read gauge with alarm functionality. - All specified values and units are kept as provided, including sensor options and display metrics, to maintain consistency with the original design and function.
