Battery Hydrometer Tester – Measures Electrolyte Density, Clear Housing, Color‑Coded ScaleProduct AttributesSize: 11.02*2.83*1.90 inchWeight: 3.78 ozColor: BlackMaterial: Silicone + PSPackaging: 1x Battery Hydrometer TesterPackage Sizes: 10.12*5.83*2.11 inchUsage NotesKeep the black plastic float centered vertically during measurementDraw in enough battery fluid so the level sits above the lowest mark on the tubeFeaturesDurable BuildPS casing resists impacts and aging. Silicone parts stay flexible and seal well over timeClear ReadingTransparent body with a color‑matched scale. You can see the exact density number and quickly check battery status by the color zoneDensity GuideReading Battery Condition1.275 – 1.300 Good working order – continue usingBelow 1.250 Weak condition – plan to replace soon

• Color Zone Indicators: This car battery tester has clear density scale markings. Different ranges use different color cues. When the reading falls below 1.25, gray and orange bands appear. That means you should change fresh electrolyte right away
• Reads 1.0 to 1.3 Range: Our battery tester measures from 1.0 up to 1.3. Electrolyte density is checked quickly. The state of charge is shown directly. You can better understand whether a potential issue is developing inside your battery
• 6V, 12V, 24V Support: This battery tester 12v automotive works across multiple voltage systems. Use it on 6V, 12V, or 24V vehicle batteries. Electrolyte density measurement is supported on all three. Quick and accurate health checks for your battery
• Suction and Float Method: Draw battery fluid into the car battery tester until it passes the horizontal minimum mark. Keep the black float aligned with the centerline during measurement. A reading between 1.275 and 1.300 means your battery is in good shape
• Clear Plastic Shell: The battery hydrometer tester uses a highly transparent shell. Deformation and cracking are unlikely. The connecting tube and end suction parts use quality sealing rubber. Fast, accurate specific gravity readings are displayed every time
