Using the Gradient Column Method, the Ray-Ran Density Gradient Apparatus can calulate the density of a specimen to 6 decimal places and become the worlds benchmark fore accurate density measurement.

The Advanced Auto Density Gradient Apparatus from Ray-Ran has become the world’s benchmark for accurate density measurement of small solid specimens using the column method. Built with operator simplicity in mind, its ease of operation and high accuracy makes it ideal for product development and quality control within production, research and development labs and teaching institutions.

Offered as a 3 or 6 column version, the built-in on-board Microprocessor System accurately calculates the specimen’s density to a resolution of 0.001g/ml more quickly and more accurately by measuring the samples position in the column relative to the calibrated marker floats. Once the correct position of the sample is recorded the density is displayed on the LCD screen. Column linearity can also be checked and shown in Techni-test software.

The on-board LCD provides simple on-screen instruction and using the alpha/numeric keypad test parameters such as operator list, material reference numbers and batch numbers can be entered and stored for results presentation. Batch statistics of mean, standard deviation and co-efficient of variation are automatically updated after each test and results are shown in graphical and tabular format for analysis when downloaded to the supplied Techni-Test PC software.
