Accurately determining the concentration of dissolved salt in liquids is a critical step in food processing, marine biology, and industrial manufacturing. VEE GEE 6611 Series Sodium Chloride Hydrometers are precision borosilicate glass instruments designed to quickly measure NaCl levels in solutions with an accuracy of ±1 subdivision. Whether you require a reading based on total saturation percentage or percentage by weight, these hydrometers provide clear, easy-to-read results. Proudly Made in the USA and calibrated at 15.5°C (60°F) to ensure consistent quality control data. Features and Benefits Targeted NaCl Measurement: Specifically engineered and calibrated to measure the concentration of sodium chloride in aqueous solutions with ±1 subdivision accuracy. Standardized Calibration: Precisely calibrated for use at 15.5°C (60°F) to ensure repeatable accuracy across routine testing environments. Premium Borosilicate Glass: Constructed from durable, transparent borosilicate glass with high-contrast printed scales for fast visual readings without eye strain. Two Scale Options: Available in Percentage Saturation (0–100%, 1.0% subdivisions) and Percentage by Weight (0–26.5%, 0.5% subdivisions) to match your specific procedural requirements. Proudly Made in the USA: Manufactured domestically under strict quality controls to ensure structural integrity and calibration precision.

If you need the physical weight ratio of salt to water, choose the Percentage by Weight model (6611-2, 0.5% subdivisions). Do these hydrometers have a built-in thermometer?No, the 6611 Series does not include an integrated thermometer. You will need to ensure your sample liquid is at the calibration temperature of 15.5°C (60°F) or use a separate thermometer and correction table. Can this measure other types of salts?These instruments are specifically calibrated for Sodium Chloride (NaCl). While they will sink or float in other solutions, the printed scale will not provide an accurate concentration reading for differing chemical compounds. For Calcium Chloride testing, see the VEE GEE 6611-3. What hydrometer cylinder do I need?VEE GEE recommends the 66CS-13 polycarbonate hydrometer cylinder or the 66CS-13J glass hydrometer jar for use with the 6611 Series. Quality Assurance VEE GEE Scientific hydrometers are manufactured in the United States from premium borosilicate glass and are individually inspected against NIST-traceable standards to ensure reliable, highly accurate performance across scientific disciplines.
