Stiffness Tester For Paper

The stiffness of the paper is an important factor when it comes to determining its quality. Therefore, you can easily measure the stiffness of paper with the help of the Presto stiffness tester. Paper and board industries can use this tool for measuring the flexural strength of their products, which ultimately helps them in deciding the price and quality of their product This tool is a must-have for any industry that makes or uses paper and boards because it does not only measure but also calculates the stiffness value with great precision. It has been designed in such a way that even beginners will find it easy to use. Anyone who wants to know about the rigidity of his/her product can get accurate results from this testing machine.

We understand that the stiffness of paper and its boards are an important factor in determining the quality. This property decides the economic value of the product. There are various methods to determine this property, but they do not give accurate results all the time. So it becomes difficult to judge whether a particular sample is good or bad. It also takes a lot of time and effort to measure this property using these conventional methods. With Presto’s stiff resistance tester, measuring flexural rigidity has become easier than ever before. It gives accurate results every single time because it uses advanced technology for measurement which makes it more reliable than other existing methods like manual testing. This device saves both your money and your valuable time by providing you with precise data within seconds. This product is widely used to manufacture various products like boxes, folders, etc. It’s very difficult to determine the quality of paper and paper boards using conventional methods. The stiffness tester can be used for this purpose as it gives accurate results with high precision. Presto offers a wide range of stiff resistance testers which are highly efficient and easy to use even by beginners. These testers provide reliable measurement results within seconds without any user calibration or adjustment required. They also come at an affordable price so that they can be afforded by small-scale industries as well as large-scale industries too.

The flexural rigidity is an important property of the paper and it decides its economic value. It is one of the most difficult properties to measure. This tester can be used for measuring flexural strength and stiffness of various materials like papers, boards, etc. This equipment uses a standard load cell with a precision digital display unit along with a force gauge for reading results accurately. It has an ergonomic design that makes it easy to operate by anyone even without any prior training on using it properly. The software installed in this device helps you analyze the data collected from different tests quickly so that you do not have to go through tedious calculations while doing your job efficiently. One should always buy a product that has all the required features and qualities that can help them in their work. Presto’s Stiffness Tester utilizes a two-directional pendulum-type weighing system to evaluate material stiffness, flexural strength, and resiliency, and elasticity properties. Force is applied to the lower end of the specimen by a pair of rollers attached to the driving disc. The resulting torque tilts the pendulum from its vertical position and the Stiffness Unit reading (g/cm) is taken when the pendulum mark aligns with the appropriate driving disc mark (15°). Predetermined sample length, deflection angle, and rate of loading provide accurate and reproducible test results. An established tester offers durable construction.

Presto Stiffness Tester offers telescoping tripod legs which make this instrument lightweight and portable. Operated manually by a lever control switch, a robust housing protects the electrical components. The new ratchet stop roller significantly reduces specimen mounting variability. Nine distinct setups permit the testing of very delicate to extremely rigid materials. Presto Stiffness Tester is used to evaluate the paper, foil, light metallic sheet, laminated plastic, cardboard, wire, and other flexible materials up to 5.5mm (0.219 inches) thick that do not exceed 10,000 Stiffness Units. To operate this machine, you need to follow the below-mentioned steps:

• If you want to perform the stiffness test with the Presto stiffness tester, then you need to install the machine properly. For this, you need to place the machine on a Flat Base and ensure that all legs are aligned at the time of unloading. At the time of loading, it is not necessary that the sample is aligned.
• After that, you need to prepare the sample by taking a piece of paper that the user needs to test and cutting the sample according to the template. The user will get the sample of size 70mm±1mm x 38.1mm ± 0.1mm (L x W).
• Once you follow all the above steps, then you can commence the test.

Features of Stiffness Tester For Paper

Assessing the flexural strength of materials of the paper and linear boards or paper boards is important as it decides the economic value of the paper. This test can be done with our testing instrument because all our products are made up of industry standards. This testing machine is compiled with testing standards of TAPPI – T489 OM-08. To test the paper, the specimen is mounted on the tester using the clamping system. Located at the pendulum, the lower faces of the clamp jaws are at the center. The jaws adjust themselves according to the different thicknesses of the test paper. To get accurate test results, the test and angle of deflection are kept constant. To get the value of the test, the load is applied to the lower end of the specimen. It is the perfect way to determine the quality of the paper. Stiff resistance tester helps in segregating the substandard paper from the high quality. It is one of the most important test instruments used in the paper industry. Presto offers this instrument at very competitive prices. A calibration certificate is provided along with the instrument. This certificate is valid for one year.
