Product Description
Determining clay and fine particle content is a core step in soil classification. This ASTM 152H hydrometer reads soil colloids directly in grams per liter of suspension, letting soil labs calculate particle size distribution quickly without converting from specific gravity readings. It is a long-standing standard tool in soil science.
This listing is for catalog number 67152H: Soil Hydrometer, Soil Colloids, ASTM 152H, -5 to 60g, 280 mm. Made to ASTM specifications, the glass hydrometer covers -5 to 60 grams with 1.0 gram subdivisions and is calibrated at 20°C (68°F). It is 280 mm long and is used with a sedimentation cylinder, where readings are recorded at timed intervals as particles settle. It is widely specified in soil texture and hydrometer analysis procedures. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
