The gradient column method accurately measures the density of small solid materials, in various forms, Pellets, Granules, film etc..and conforms to the ASTM D1505 & ISO 1183 Method D standards.
The density is formed by mixing two fluids having different densities. The resulting solution has a density which when introduced into the column increases uniformly from top to bottom.
Ray-Ran’s new advancement means that density measurements can be made more quickly and more accurately.
The height of the calibrated marker floats or samples introduced into the density gradient are measured using a trammel guided “sight” connected to a positional encoder relaying the height position to a microprocessor so that the density can be obtained without the need for graphs etc.
This also means that the Gradient can be calibrated & checked at any time.
