Most manufacturers know that accurately determining the density of raw materials is a critical part of the production process. Why is it so important? It can help control the quality of the final product, and it can help control materials for production and processing. In some industries, it can mean the difference between profit and loss.
Adam Equipment’s density kit is a valuable tool to help manufacturers accurately determine the density of their materials. Combine the density kit with the Adam PW analytical balance and the process becomes even more reliable and precise.
Traditionally, density determination has required measuring the sample material: figuring out the volume, weighing the sample, dividing the volume by the mass, and finally coming up with the density. The process is not only complicated and tedious; it is far less accurate, especially when the shape of the raw material is irregular.
Testing of both solids and liquids is possible using the density kit. That means that even samples with densities greater or less than that of water can be determined. The balance software will calculate density using water, ethanol or paraffin as selectable references. The software also allows the user to enter the density of any reference liquid directly.
The density kit is installed on the floor of the PW’s enclosed weighing chamber. The kit’s beaker holds the reference liquid and may be reused to test as many samples as needed. The user simply selects the density application from the built-in menu options. If a reference liquid is used other than what is already programmed into the balance, the user can enter the density for that reference liquid. The application prompts the user through the process: weigh the sample in air using the sample cup on top of the stand, then in the reference liquid using the sample cup suspended on the wire. The balance software calculates the density automatically.
Shown with Adam Equipment’s PW analytical balance, the density kit consists of a glass beaker, a suspended weighing cradle to replace the standard pan, independent support for the beaker of fluid, thermometer with clip for suspension in the fluid and glass sinker of known volume for determination of fluid density.
Adam’s PW analytical balances offer a quick and easy way to measure to 0.1mg. The PW provides 16 weighing units, including a custom unit and features durable metal construction, standard internal motorized calibration and a large backlit dual display that shows text prompts to help the user set up the balance quickly. Highlighted tare keys stand out for accessibility, while other buttons operate set-up functions, turn the balance on or off, send data to a printer, calibrate and change modes and weighing units.
The bi-directional RS-232 interface enables data transfer from the balance to printers or computers. This allows foolproof data recording and traceability, letting the operator focus on data analysis. Other useful features include built-in applications for density, percentage, comparison and check weighing, plus counting and dynamic or animal weighing.
