How A Pull Off Adhesion Tester Works?

A pull-off tester measures coating adhesion to rigid substances like wood, concrete, and metal. It relies on a hydraulic system to pull away a test disk which is glued to the substrate material. The tester records the force applied when failure occurs. The pull off adhesion tester is widely used in quality assurance in construction to save time, as it is a reliable means to make sure that there is enough adhesion between the substrate and the coating. Here’s how the device works:

  • Manual mode - The tester is available in both automatic and manual modes. The manual hydraulic pump applies continuous and smooth pressure using a single stroke. Use the pull rate indicator to monitor and adjust the rate of pull manually. The internal memory can store the maximum pull-off pressure, test duration, rate of pull, and the dolly size for a maximum of 200 pulls. A manual pull off adhesion tester is compatible with PosiSoft software, so you can interpret or refer to the results on your computer.

  • Automatic mode – The automatic pull off adhesion tester has a rugged colour touch screen that can resist scratches and impact. The keypad will work even if you are wearing gloves. The automatic tester uses an electronically controlled hydraulic pump to automatically apply continuous and smooth pull-off pressure, reducing your need to exert effort and the risk of operators affecting the pulling process. You can adjust the pull rate, hold time, and pull limit, and take it with you on the field as it comes with a built-in rechargeable battery which should be good for more than 200 tests per charge. It can run on AC power even as the battery is recharging.
The internal memory can store the same details as the manual pull off adhesion tester , along with additional factors like user notes for thousands of pulls, the nature of the fracture, and pass/fail. The newest release testers come with Wi-Fi technology and Bluetooth.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr

Precautions to Be Taken While Using a Piezometer

The piezometer is a measuring device that determines pore pressures underground and liquid pressure. By determining pore pressure, you can understand the behaviour of the ground before, during, and after a construction project. Certain precautions must be taken when using a piezometer to ensure proper usage and the accuracy of results. Here are some of them: Have the right equipment – Invest in a state-of-the-art piezometer that uses a proven method of converting fluid pressures on the sensitive diaphragm into frequency signals which are ideal in the demanding environment common with civil engineering applications. Modern piezometers are capable of long distance signal transmission without degradation. They can tolerate wet wiring conditions and resist external electrical noise, too. Some manufacturers make piezometers specific for different applications, for instance, you should be able to find one with a heavy-duty body that can be b
