E-Z Red S101 Battery Hydrometer Acid Tester

The E-Z Red S101 Battery Hydrometer is an essential diagnostic tool for testing the specific gravity and charge level of lead-acid batteries. This precision instrument draws battery electrolyte into a graduated float chamber, providing accurate readings that help determine battery health and state of charge.

Key Features:

• Easy-to-read color-coded float scale for quick charge assessment
• Durable construction with chemical-resistant materials
• Flexible draw tube for accessing hard-to-reach battery cells
• Accurate specific gravity readings from 1.100 to 1.300
• Includes detailed instructions for proper testing procedure

Essential for automotive, marine, and RV battery maintenance, this hydrometer helps identify weak cells, sulfation, and charging system problems before they lead to battery failure. Regular testing with this tool can extend battery life and prevent unexpected breakdowns.
