VEE GEE Scientific Specific Gravity Hydrometer with Integrated Thermometer 385mm

Every specific gravity measurement is incomplete without temperature — the same solution at 15°C and 25°C will produce different hydrometer readings, and applying the correct temperature correction requires knowing both values simultaneously. The VEE GEE Scientific 6602TS Specific Gravity Hydrometer with Integrated Thermometer builds a SafetyBLUE liquid-in-glass thermometer directly into the hydrometer stem, displaying both specific gravity and temperature from a single instrument dip. No separate thermometer, no second cylinder, no synchronized timing — one reading captures both measurements.

Available in two overlapping 0.070-unit ranges (1.000–1.070 and 1.060–1.130) with 0.001 SG subdivisions — covering the dilute solution, wastewater, light brine, and dilute acid applications where temperature-corrected SG measurement is most commonly required. The integrated SafetyBLUE thermometer fill is mercury-free, organic, and non-toxic. Calibrated at 15°C/60°F.

Features and Benefits

• Integrated SafetyBLUE Thermometer: An internal SafetyBLUE liquid-in-glass thermometer is built into the hydrometer stem — reads temperature simultaneously with specific gravity, eliminating the need for a separate thermometer and allowing temperature correction to be applied immediately.

• 0.001 Subdivisions: Fine 0.001 SG resolution across a 0.07-unit range — same precision as the standard 6602-series but with the added temperature measurement built in.

• 385 mm (15.2 in) Length: Longer than standard hydrometers to accommodate the combined specific gravity scale and thermometer column — requires an appropriately sized hydrometer cylinder.

• Calibrated at 15°C/60°F: Reference calibration compatible with international and US temperature standards.

• Temperature Range on Thermometer: Internal thermometer displays temperature for direct temperature-corrected specific gravity determination without manual calculation.

• 1-Year Warranty: VEE GEE Scientific instrument warranty.

Specifications by Model

Laboratory Applications

• Wastewater and environmental monitoring where temperature-corrected specific gravity determines solution concentration in the field without a second instrument

• Brewing and fermentation — original gravity measurement with simultaneous temperature reading for immediate correction to standard reference gravity

• Dilute acid and electrolyte process monitoring where temperature variation from process heating makes uncorrected SG measurements unreliable

• Battery electrolyte monitoring in small cells where the combined instrument reduces the number of measurement steps

Frequently Asked Questions

What temperature range does the integrated thermometer cover?
The thermometer range is listed in the product specifications — typically covering the working temperature range for dilute solution applications (approximately 0–50°C). Check the product spec sheet for the exact thermometer scale range.

How do I use the temperature reading to correct my SG measurement?
For most aqueous solutions, apply the standard temperature correction: SG(corrected) = SG(measured) + 0.0003 × (T_measured - T_reference), where T_reference is 15°C. More precise corrections use solution-specific tables available from reference sources. The integrated thermometer eliminates the time delay between measuring SG and reading temperature from a separate instrument.

These are longer than standard hydrometers — will they fit in my cylinder?
6602TS instruments are 385 mm (15.2 in) — longer than standard 305 mm hydrometers. Confirm your hydrometer cylinder accommodates at least 400 mm length. Standard 500 mL graduated cylinders (typically 380–420 mm tall) usually accommodate this instrument with a few mm to spare.

Quality Assurance

VEE GEE Scientific manufactures 6602TS hydrometers with permanently graduated glass scales and integrated SafetyBLUE thermometer fills. Both the SG scale and thermometer are calibrated at 15°C/60°F reference temperature. Mercury-free SafetyBLUE fill is non-toxic and biodegradable. Backed by a 1-year warranty.
