  • The TM-85 Soil Hydrometer is a laboratory instrument used to determine the particle density (specific gravity) of soil, designed based on Stokes' Law. Its principle involves measuring the settling velocity of soil particles in still water and combining it with the particle size distribution to calculate the soil's specific gravity. It is suitable for particle size analysis of fine-grained soils, such as clay and silt..

The market is split between high-precision glass instruments for labs and more rugged, affordable tools for home brewing and construction site testing.

Buying Guide: laboratory hydrometers

AI
When shopping for a hydrometer, prioritize the measurement range and the precision of the scale divisions to ensure they match your project's tolerances.

Selection Criteria

Products were selected based on technical accuracy, material durability, user feedback regarding readability, and overall value for the price point.

Budget Advice

AI
Entry-level tools for home use are very affordable, while mid-range professional glass instruments and premium construction-grade kits cost significantly more.

Conclusion: laboratory hydrometers

AI
Choosing a hydrometer depends entirely on your specific measurement needs and the density of your liquids. To find the tool that fits your technical requirements, explore our full list of top-rated options.

Frequently Asked Questions

AI
Specific gravity hydrometers measure the density of a liquid relative to water, making them versatile for various chemicals. Proof hydrometers are specialized for alcohol concentration, providing readings in proof or percentage.
Yes, a graduated cylinder or a dedicated test jar is essential. The jar must be tall and wide enough to allow the hydrometer to float freely without touching the sides, which would skew the reading.
Ensure the liquid is at the temperature specified on the instrument's scale. If the liquid is too hot or cold, you will need to apply a temperature correction factor to the result.
