The GSM round cutter is one of the precise testing instruments designed by experts at Testronix, that will help you in the accurate cutting of specimens. It is the most recommendable testing instrument used in the fabric industry to calculate the GSM of materials. The sample cutter cuts out a circular specimen of 100 Cm2, which is exactly 1 / 100th of a square meter, rapidly and accurately. The result is in grams, multiplied by 100, and gives the GSM (Grams per square meter) directly. The main purpose of the GSM round cutter is to ensure that you will get a precise cutting of specimen. It comes with 4 built-in knives which are sharp enough to cut the specimen accurately and precisely. In the consumer textile testing labs, the use of GSM round cutters is most common. This will help to ensure that you will easily measure the GSM of fabrics with the accurate cutting of the specimen.

How does the GSM round cutter work?

To accurately cut the sample with the help of a GSM round cutter, you can easily place it on the sample cutting pad. Release or open the safety pin with the slight pressure on the handles to bring internal blades in contact with the sample. You can easily cut the samples by rotating the handle under pressure. The design of the instrument is such that the specimens are removed cleanly and have smooth edges.

In this way, you can accurately cut the testing sample and calculate the GSM of it. Thus, you can consider the GSM of fabric or paper by accurately cutting the sample with the help of a GSM round cutter.
