Eliminate the worry of loose bottle caps with the Presto torque tester

bottle caps

PET bottle quality testing is very important to make sure that the right product is delivered to customers with ease. It helps to ensure that the products packed in PET bottles meet the required standards and specifications. Various tests are conducted on PET bottles to check their strength, durability, and safety. The most common test conducted on PET bottles is the torque test for caps. This can be done with the help of a Presto torque tester which is one of the consistent testing equipment to measure the force required to open a closed cap of a PET bottle. This lab testing equipment will provide you with the torque value in digital format. It comes with a high-end sophisticated read-out with Auto Tare (zero) set facility and peak hold management.

Here in this blog, we are going to provide you with information about how you can easily test the torque strength of PET bottle caps with the help of torque testing equipment. So, let us get started!

Introduction about torque tester

torque tester is a highly sophisticated testing instrument that is designed to provide an accurate analysis of the force or torque needed to open a closed cap of a PET bottle.

This testing instrument is highly useful in studying the efficiency of bottle caps in the PET industry. The principle of operation of the torque tester is based on the measurement of the amount of torque required to open a sealed cap.

It has been equipped with a digital display that shows the exact value of the force or torque required to open the cap. The digital display also helps in recording the value for further analysis. The instrument is very easy to use and provides accurate results. This lab testing instrument will also help the manufacturers to ensure the bottle caps are tightened and can be opened with the optimum force when applied to them.

Purpose of conducting torque test on PET bottles

The Presto torque tester will be an accurate testing instrument that has been provided with a high-quality torque sensor to examine the force required to open the cap of PET bottles. This testing instrument will also ensure that the bottles will be safe to use. It has been widely used in the PET bottle manufacturing industry and tests the torque needed to open a closed PET bottle cap.

With manual clamping and operation, this torque testing equipment comes with a digital read-out with the least count of 0.1 lbs-inch. You can read more about its features below.
