Hydrometer testing determines complete particle size distribution in soils and for dispersing soil suspensions. The heavy-duty unit operates at a speed above 10,000 RPM. The soil hydrometer jar measures suspended solids in sedimentation cylinders over time periods of 24 hours. Soil specimens mix in a solution of water and sodium hexametaphosphate. The hydrometer bath provides a 68°F ambient temperature throughout the unit. Using a microprocessor-based temperature control with integral heater and chiller. In addition, the bath comes fully insulated and has a capacity of 8 hydrometer jars.
