The calculation of GSM or grammage per square is significant when it comes to measuring the basis weight of a paper or packaging material. To do this, manufacturers either make use of a competent GSM tester or a high-quality quadrant paper scale. Both instruments are crucial for the successful determination of GSM, however, in this blog, we will throw light on the capacities of a quadrant scale. So, let’s go.
What is a Quadrant Paper Scale?
As the name suggests, a quadrant scale is an instrument that measures the Basis weight of paper, board, or similar materials. The test unit accepts a small test sample to perform the test, prepared using a square paper cutter. On this sample cutter, each specimen is prepared in a given dimension, i.e., 10x10 cm or 20x25 cm.
Once the sample is prepared, it is brought to the scales, which are calibrated to high-accuracy dead weights. The unit maintains this accuracy until the pendulum comes to its original form.
What Factors Maintain The Accuracy Of The GSM Test?
The accuracy of the weights and the presence of a competent square paper cutter are crucial for this test to be successful. This is because if the weights are subjected to corrosion, deformation, or damage due to any reason, both the balance and weight will be affected. Similarly, if the sample is prepared manually and without the support of the sample cutter, the sample may get damaged during the test or give inaccurate results.
How Versatile Is A Quadrant Scale?
A Quadrant paper scale is versatile enough to weigh paper, fabric, board, and materials of similar kinds. In the paper category, the scale can measure the basis weight of newsprint, writing paper, printing or copier paper, duplex and art paper, tissue, and other soft materials. Besides, it can measure the GSM of Kraft liner/fluting paper, corrugated fibre board, box board, and sack material in the board category.
Besides, the GSM measuring range available in a quadrant scale is 0 to 125, 250, 500, and 1000 GSM. This means that the unit is compatible with measuring a paper or material of the above GSM range. The only thing manufacturers must make sure of is that they are buying this equipment from a reputed and reliable company like UEC. The scale offered by this company is certified under TAPPI, ISO, SCAN, APPITA, & JIS standards.
Bottom Line
Just like the GSM tester, the quadrant paper scale is capable of serving manufacturers producing a varied range of paper and materials. If you’re looking forward to investing in a high-quality quadrant scale, visit the official website of UEC and get in touch with the experts.
