## Summary description

Glass-flask hydrometer Forsage F-9G4005A designed to measure the specific gravity of battery electrolyte. This cylinder-style hydrometer provides direct readings of electrolyte density for lead‑acid battery maintenance, helping assess state of charge and detect sulfation. Suitable for workshop and roadside battery checks where quick, manual density measurements are needed.

## Long description

Glass-flask hydrometer Forsage F-9G4005A is designed to measure the specific gravity of battery electrolyte in lead‑acid batteries. The instrument consists of a calibrated glass cylinder with an internal float, providing direct, manual readings of electrolyte density. It is suitable for routine maintenance, rapid state-of-charge checks and detection of electrolyte stratification or sulfation in workshop and roadside conditions.
Advantages
The hydrometer offers a simple, mechanical design that requires no power source and gives immediate visual readings. Its glass construction ensures chemical resistance to battery acid and clear visibility of the float scale. The cylinder-style form factor allows for straightforward sampling and reliable repeatability when used correctly. The tool is compact and portable for use in both stationary workshops and mobile service situations.
Suitable for
 Measuring electrolyte specific gravity in lead‑acid batteries
 Routine battery maintenance and preventive checks
 Quick state-of-charge assessments for vehicles and equipment
 Detecting sulfation or electrolyte stratification in battery cells
Key specifications
 Design: glass cylinder (flask) with internal float and calibrated scale
 Measurement: direct visual reading of electrolyte specific gravity
 Material: acid-resistant glass
 Operation: manual, no batteries or power required
 Portability: compact, handheld form factor for workshop or roadside use
How to use
Wear appropriate eye and hand protection. Draw a sample of electrolyte into the glass cylinder, ensuring the float is free to settle without contacting the cylinder walls. Read the value at the electrolyte surface level against the float’s calibrated scale to determine specific gravity. After measurement, carefully return the sample to the battery cell if required by the battery type and safety guidance, or dispose of it according to local regulations for acidic liquids. Rinse the hydrometer with distilled water between samples to avoid cross-contamination.
Usage recommendations
Use the hydrometer at ambient temperature or apply temperature correction where necessary; consult battery manufacturer guidelines for specific gravity values corresponding to state of charge. Avoid introducing contaminants into the battery electrolyte, and store the glass hydrometer in a padded container to prevent breakage.
