Product Description<\/span>
\nDigital Readout Density Column.<\/span> – 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.<\/span><\/p>\n

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.<\/p>\n

Ray-Ran’s new advancement means that density measurements can be made more quickly and more accurately.<\/p>\n

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.<\/p>\n

This also means that the Gradient can be calibrated & checked at any time.<\/p>\n

Standard features include.<\/span>
\nMicroprocessor System to accurately calculate the Density of the Sample. Twin conical flask pumped filling apparatus with motorised magnetic stirrer, Automatic column clearing device – sweep basket arrested automatically at top and bottom of column and pivoted for use over any of the 3 columns, Digital Temperature Controller accurate to +\/- 0.1 \ufffdC, RS232 output, Built-in cooling coil, black or white twin background to assist sighting different colour samples, Microprocessor Auto Calibration System, Fully traceable certificate of calibration, Product user manual, CE mark of conformity<\/p>\n

Optional accessories available.<\/span>
\nMicroprocessor Controlled Filling System, Water chiller unit, glass marker floats, Thermal printer<\/p>\n

<\/p>\n

Test Description<\/span>
\nWhen a sample material is placed in the density column its height in the column is measured using the trammel system “sight” and the microprocessor then calculates the corresponding density.<\/span><\/p>\n
