Feature: 1. Accurate Indication: Engine speed 0‑4000RPM, water temperature value of engine water tank 40‑120℃ (100‑250℉), remaining fuel amount in fuel tank E‑1/2‑F, fuel tank fuel pressure value 0‑145PSI (0‑10Bar) , the voltmeter displays the voltage 0‑38V through the specific value, with red backlight for easy viewing at night. 2. Durable Structure: 316L stainless steel front cover bezel, anti fog curved glass cover and industrial grade electronic components structure. The shell is made of aluminum plate and baking paint process, which is anti oxidant and can be used normally even in acid base and humid environments. Anti fog, IP67 waterproof and dustproof, which is very suitable for sea and various harsh environments. 3. High Performance: Post programming technology, the driver can be modified as needed to match a variety of analog input signals. The pointer is driven by a stepping motor, and the pointer display has the characteristics of high indicating accuracy, good repeatability, strong versatility, reliability and stability, and easy to use. 4. Compact and Functional: Only 200x335mm unit area can be combined with 5 meters, which greatly saves the use space. With ignition start indicator, light switch, engine stop switch, BZ ST switch, water temperature alarm, oil pressure alarm, battery charge alarm, you can know the status of the engine at any time through the data of the meter. 5. Professional Design: The whole gauge cluster combination surface panels adopts ultra wide working voltage design, long term working voltage is 9‑32V, up to 36V (≤1 minute), ultra low power consumption design, the working current of the 52mm series small gauge does not exceed 60mA, and the working current of the 85mm series large gauge does not exceed 100mA. 6. Usages: Used in engines, generator sets, RVs, trucks, work vehicles, yachts, fishing boats, ships, construction machinery, agricultural machinery, modified vehicles and other fields. The wiring harness connector has a snap, which can ensure a firm connection between the instrument and the wiring harness, and it can still work reliably even in situations with strong vibration.
