Key features

• •Double Tips: Car battery tester with clear density scale mark, and different scale stalls also have different color tips, when the measured value is less than 1.25, the color indication of gray and orange, you need to replace the electrolyte immediately
• •Fast Readings: Our battery tester can measure from 1 to 1.3, allowing quickly check the battery electrolyte density, directly reflecting the state of charge of the battery and helping you to better understand if there is a potential failure in the battery
• •Multi-Voltage Application: Our battery tester 12v automotive can be used to measure the electrolyte density of vehicle batteries with voltages of 6V, 12V and 24V, helping you to make an accurate and quick judgment on the health of the battery
• •How to Use: Simply suck in the battery fluid until it is above the horizontal minimum level line, keep the black buoy aligned perpendicular to the centerline when measuring, if the measured value is 1.275-1.300, the battery is in good condition
• •Premium Material: The battery hydrometer tester shell is made of highly transparent material, not easy to deform and crack. Connecting tube and sunction at both ends made of outstanding sealing rubber for fast and accurate display of specific gravity
