Product Description
Particle size analysis of soils depends on tracking how quickly particles settle out of suspension. This ASTM 151H soil hydrometer measures the specific gravity of that suspension over time, giving geotechnical and agricultural labs the data they need to classify sand, silt and clay fractions reliably.
This listing is for catalog number 67151H: Soil Hydrometer, Specific Gravity, ASTM 151H, 0.995 to 1.038, 280 mm. Made to ASTM specifications, the glass hydrometer reads specific gravity from 0.995 to 1.038 in 0.001 steps and is calibrated at 20°C (68°F). At 280 mm long, it is designed for use with a sedimentation cylinder, where readings are taken at set intervals as particles settle. It is a standard instrument for the soil hydrometer test method. Add it to your LIGHT LABS order and keep your lab stocked.
