Many packaging containers will require different means of closing. If you want to make sure that your container will be closed enough to make sure that the contents will not get spilled then you should make the use of the Testronix torque tester. This lab testing equipment is highly useful to calculate the force/torque that will be required to open regular screwed closures present in bottles. It has been designed with the latest cutting-edge technology and comes with an advanced set of features to calculate the opening and closing torque. Here we are going to discuss more torque testing equipment and how you can easily test the quality of regular screwed closures. So, let us get started!

Deliver quality bottles accurately by testing them with the Testronix torque tester

The bottle screws are considered to be the simple way to seal up the jars and bottles accurately. To keep the content fresh inside the jars and bottles, it is important for you to check the regular screwed closures of these bottles. Thus, we at Testronix are considered to be the leading manufacturers of torque testers and design this highly accurate testing equipment to determine the torque needed to open a closed bottle screw.

It is a fact that most of the products that are stored or packed in PET bottles are mainly in liquid form. They can easily be spilled over if the bottle caps will not close properly. Thus, it is important for you to test the torque needed to open/close the PET bottles efficiently. This can optimally be done with the use of a Testronix torque tester.

This lab testing instrument has especially been designed to test the torque for opening/closing the cap of the bottle. The value of the torque can easily be viewed on the digital screen instantly after the completion of the test. The units of the reading will be lb-inch. This testing instrument will also come with the additional feature of saving up to 9 test readings. This will make the torque testing procedure much easier and simpler. This testing instrument will test the fastening of lids and caps when the bottles are subjected to load under twisting. You can easily conduct the torque test of multi-way plastic bottles with the help of this lab testing equipment.

Below we have listed the features and technical specifications of this lab testing equipment.

Features of Testronix torque tester

Measuring the torque value of regular screwed bottles will help you to ensure the quality, safety as well as reliability of the product. The failure of these fasteners and screws will lead to catastrophic or latent failures. Thus torque tester from Testronix will help you to secure the exactness as well as precision of bottles before delivering them to the customers.
