1. Multifunctional: Accurately indicate the engine speed of 0-3000RPM, the water temperature of the engine water tank is 0-120°C (30-250°F), the remaining in the tank is E-1/4-1/2-3/4-F, the pressure in the tank is 0-150PSI (0-10Bar), and the voltmeter displays the voltage of 16-32V. 7 kinds of color conversion function, convenient for night viewing. 2. Switch and Alarm: The panel is equipped with ignition start indicator, lighting switch, engine stop switch, BUZZER switch and backlight color change switch Water temperature alarm, low oil pressure alarm, low voltage alarm, battery charging alarm, and the status of the engine can be known at any time through the data of the inst ent 3. Construction: Made of stainless steel front cover bezel, anti fog curved glass cover and industrial grade electronic components, which can withstand mechanical shock and vibration. It can be used normally even in acid, and humid environments. IP67 waterproof and dustproof, which is very suitable for sea and various harsh environments. The working temperature can reach - 30 -+75 ℃. 4. Ultra Wide Working Voltage Design: Long term working voltage 9-32V, ultra low power consumption design, 52mm small meter working current less than equal 60mm, 85mm large meter working current less than equal 100mA. The harness connector is equipped with clips, which can that the connection between the inst ent and the harness is firm, that is, it can still work reliably in situations with strong vibration. 5. Universal Fit: The panel can combine the 5 gauges, greatly saving the use space. The central control 5 gauge panel can be used in engines, generator sets, RV vehicles, yachts, fishing boats, ships, engineering machinery, agricultural machinery, modified vehicles and other fields.
