How to Calibrate the Top Load Tester in 5 Easy Steps

PET packaging has the ability to endure a variety of environmental factors. As a result, it has become a popular option among manufacturers and customers to store their products efficiently. Whenever you deliver your product in PET packaging containers or bottles, it is important for you to check its integrity. One of the important factors that play a role in testing the integrity of these bottles is the top load strength of these bottles or jars. This can be done with the help of Presto top load tester-Prima. This lab testing equipment is highly useful in testing the top load strength of PET products so that you can deliver quality products to your customers.

This fully-automatic motorized testing instrument will help you to generate a compressive buckling load on the products. The inverted jaws are provided with this testing instrument to make sure that the specimen will not be slipped when placed between these jaws. Thus, you can easily rely on this lab testing instrument to make sure that you will be able to deliver accurate products to the customers.

Here, we will discuss the steps to calibrate the top load tester for PET bottles. But before that, we will focus on the use of this testing instrument for PET bottles.

Perform quality research test for PET bottles using a top load tester

When it comes to delivering products securely and precisely, quality plays a crucial role in it. When PET bottles are transported, they are piled on top of one another, resulting in compressive stresses. These compressive forces will deform the PET bottles which may result in the destruction of the product. Thus, it is important for you to test the quality of PET bottles before delivering them to the customers. Presto top-load testing instrument is one of the highly accurate lab testing equipment that will help you to test the top load strength of PET bottles or jars when they come in contact with compressive forces.

These forces will cause the bottles to deform which will help you decide whether the PET bottle you manufacture will be suitable for delivering your product or not. With the help of this lab testing instrument, you can perform the compressive test on these bottles and determine their behavior.

This load tester for bottles is considered to be a one-stop solution for testing the quality of PET bottles. Below we have discussed the advanced set of features that you will get with the use of this lab testing equipment.

Features of Presto top load tester- Prima

The Prima Series Top Load Tester is intended to test compressive buckling loads. This testing instrument is used for testing the load-bearing capacity of the PET containers when subjected to an extreme load from the top direction. It helps to determine the maximum load a PET container can bear without any deformation or failure. Thus, you can easily ensure that your PET bottles will remain compressive resistant by testing with a Presto top load tester.

Below we have listed the features of this lab testing instrument:

  • High testing range of up to 100 kgf.
  • Suitable for a testing load capacity of PET bottles, jars, and small boxes.
  • Compression plates for proper placement of the test specimen.
  • Customized speed settings for Test Speed and up-down movement of grips.
  • Data recording in tabular form as well as graphical form.
  • Easy to calibrate and operate.
  • Printout option for complete test report through Dot Printer.
  • Limit switches & emergency switch protection for the protection of grips and the machine.
  • Adjustable height and angle of HMI panel for ease of application to the user.
  • Powder-coated body with corrosion resistance.

Technical Specifications of Presto top load tester-Prima

  • Maximum Load range: 100 kgf
  • Accuracy: ±2% full scale (with master load)
  • Least Count / Resolution: 220V, Single Phase, 50 Hz
  • Power: 220V, Single Phase, 50 Hz
  • Display: HMI display with Touch Screen Controls
  • Load Monitoring: On HMI Screen

  • Over Load relay contact rating: Potential free relay 5 Amp. 220 V AC single phase

These are the features and technical specifications you will get with the help of the Presto top load tester-Prima series. The bottle is exposed to weight from the top until it exhibits buckling in this test. This test is significant since bottles carry a lot of weight during transit and stacking. If the capacity is unclear, the carrier firm will be unable to handle the goods with care. Thus, the top load test for PET bottles plays a significant role in testing their quality.

Now, let us focus on the easy-to-follow steps for calibration of this testing instrument.

5 easy steps to calibrate the top load tester efficiently

Manufacturing various sorts of containers, particularly PET bottles and jars, guarantees that items can survive the external stresses that are common while refilling, capping, stacking, and storage. Top Load Testers are available at an affordable price at Presto. We are considered to be the leading top load tester manufacturer in India. These testers assist PET product makers in measuring the top load strength of their goods using ASTM and ISO standard test techniques.

  • STEP 1: Tap the TARE button and remove all kinds of load from the lower compression plate.
  • STEP 2: Press the ZERO button on the screen, in the counter side box zero reading will see.
  • STEP 3: Now place some known standard calibrated dead weight on the lower compression plate.
  • STEP 3: Enter the known weight in the reading box on the counter side of the CALIBRATION button.
  • STEP 4: Tap the CALIBRATION button, the machine will perform calibration automatically in the AVG. TIME feed in it.
  • STEP 5: In the readings box both readings will become equal. SAVE the process.

In this way, you can easily calibrate this lab testing instrument. You can give us a call at +91 9210903903 or email us at, to know more about this lab testing equipment. Our team of technical experts will easily assist you with all your queries.
