What Is a Hydrometer?
A Hydrometer is a laboratory measuring instrument used to evaluate the density of liquids or to support sedimentation-based particle size analysis of fine-grained soils.
Liya Test offers two main product groups under this category. The first consists of 13 Density Hydrometer models covering measuring ranges from 700 to 2000. The second includes 151H and 152H Hydrometers, which are commonly used in soil sedimentation analysis.
This wide selection enables laboratories to choose a model according to the expected density range and the test procedure.
Density Hydrometers from 700 to 2000
The Liya Test Density Hydrometer range begins with LT-G0670, 700–800, and continues in consecutive 100-unit intervals up to LT-G0682, 1900–2000.
This provides a total of 13 different measuring ranges.
Choosing a hydrometer with a range close to the expected liquid density allows the operator to work within an appropriate section of the instrument scale.
All listed Density Hydrometer models have common dimensions of 30 × 30 × 300 mm and an approximate weight of 0.10 kg.
How Does a Density Hydrometer Work?
A hydrometer operates according to the buoyancy principle.
The instrument is placed carefully into the liquid and allowed to float freely. The depth at which it stabilises depends on the density of the liquid.
The operator then reads the scale at the appropriate liquid level according to the test method.
Liquids with different densities cause the hydrometer to float at different positions. For this reason, selecting the correct measuring range is essential for convenient and readable measurements.
151H Hydrometer
The LT-S0005/4 Hydrometer 151H is listed with a measuring range of 0.995–1.038 and a graduation of 0.001.
This type of hydrometer is used in sedimentation-based soil analysis where the density or specific gravity of the soil-water suspension changes as particles settle.
The hydrometer readings taken at specified times provide information that can be used during particle size distribution calculations.
152H Hydrometer
The LT-S0005/5 Hydrometer 152H provides a scale from -5 to +60 g/L with 1 g/L graduation.
The 152H model is another common option for sedimentation analysis of fine soil particles. Instead of the specific gravity-type scale used by the 151H model, the 152H scale expresses suspension concentration in grams per litre.
The selected hydrometer type should therefore match the calculation method and laboratory procedure being followed.
Hydrometer Analysis of Fine-Grained Soils
Hydrometer analysis is particularly useful for soil particles that are too small to be separated effectively by conventional sieving alone.
The prepared soil suspension is transferred into a sedimentation cylinder. As the particles settle, larger particles generally descend more rapidly while smaller particles remain suspended for longer periods.
Hydrometer readings are taken at defined times. These measurements are then evaluated together with temperature, elapsed time and other test parameters to estimate the distribution of fine particle sizes.
The current ASTM method associated with sedimentation analysis of fine-grained soils is ASTM D7928.
Choosing the Correct Hydrometer
The correct model depends primarily on the application.
For general liquid density measurements, users should select one of the 13 Density Hydrometer ranges according to the expected density.
For soil sedimentation analysis, the laboratory procedure may require either a 151H or 152H model.
Important selection factors include:
- expected density range
- test method
- scale type
- required graduation
- sample temperature
- suspension properties
Using the appropriate hydrometer improves readability and helps the laboratory follow the selected test method correctly.
Laboratory Applications
The Liya Test Hydrometer range can support:
- liquid density measurements
- specific gravity-related laboratory checks
- fine-grained soil sedimentation analysis
- particle size distribution studies
- geotechnical laboratories
- soil classification laboratories
- educational and research laboratories
Overall, the Hydrometer product group combines 13 Density Hydrometers together with 151H and 152H soil-analysis models, providing a broad selection for density measurements and sedimentation-based laboratory applications.
