Battery Hydrometer Lightweight Electric Density Meter 1.10-1.30 Range Portable Tool for Solar Power System Battery Test

### Product Features 1. High Precision Corrosion-Resistant Measuring Core: Crafted from high-purity borosilicate glass, this core is fully resistant to sulfuric acid electrolyte corrosion, with ultra-stable physical properties that eliminate measurement deviations caused by material deformation. You can get reliable electrolyte density data to accurately judge the actual performance of your battery. 2. Durable Acid-Resistant Suction Bulb: Made of high-density acid-proof rubber, it has excellent sealing performance and a comfortable elastic hand feel. It can easily suck and discharge electrolyte, and will not age or crack even after long-term contact with corrosive liquids, greatly extending the service life of the product. 3. Intuitive Color-Coded Clear Scale: Printed on the transparent glass tube with wear-resistant waterproof ink, it covers the standard 1.100-1.300 measuring range with distinct red, green and yellow distinction marks. You can read the result directly without extra calculation, and quickly identify whether the battery is in good, fair or poor condition. 4. Leak-Proof Sealed Connection Structure: The glass tube and rubber suction bulb are connected with a high-precision fitting process with no reserved gaps. It prevents corrosive electrolyte from leaking during operation, effectively protecting users from chemical contact and ensuring operation safety. 5. Portable Anti-Impact Structure: The thickened glass tube body has good resistance to slight collisions, matched with a lightweight rubber bulb, the whole product is compact and easy to carry. It is suitable for outdoor or mobile repair scenarios, and no extra complex maintenance is required for daily use.
