A gradient heat seal tester is used to determine the heat seal ability of various surfaces, sealant layers of film, laminates, composites, polymers etc. The heat seal strength is expressed as a function of temperature, time and pressure. Qualitest supplies a state of the art Gradient Heat Seal Tester – QT-GHS for heat seal testing that is compliant with ASTM F2029, QB/T 2358 and YBB 00122003.
Digital force gauges are used in many different industries for tension and compression measurement. Qualitest supplies state of the art digital force gauges that can be used from the most basic to the most advanced applications.
When companies use pipes in their operations, such as transporting natural resources through pipes, it is important that the pipes are tested for quality control to guarantee that they function seamlessly. Qualitest is a top global source for testing solutions to ensure that pipes have the proper integrity and durability for their real world application.
When producing plastic pipes for infrastructure, the quality of the plastic must be good enough to withstand high levels of stress over long periods of usage. To ensure that plastic pipes are suitable for the task, Qualitest offers two state-of-the-art testing instruments for pipe manufacturers, research laboratories, and inspection institutions.
When selecting plastic materials for high-quality products, such as automobiles and airplanes, manufacturers must account for their sensitivity to high temperatures. To ensure that plastic products can withstand the rigors of their real-world application, manufacturers can measure the softening point of the material (VICAT softening temperature, or VST) and the temperature at which a sample deforms (heat deflection temperature, or HDT).

If plastic pipes are not made properly, hydrostatic pressure can cause them to burst. To determine the resistance of thermoplastic pipes, a hydrostatic pressure testing system subjects the pipes to constant internal water pressure at a constant temperature. Qualitest's Hydrostatic Pressure Tester provides user-friendly and accurate results to test the strength of thermoplastic pipes.
The QualiPERM Blaine Air Permeability Tester is the ideal instrument for measuring the fineness of the cement, which companies do to determine such qualities such as speed of setting and rate of strength development. The Tester works by applying air pressure through a sample under pre-defined conditions to simulate different industrial standards.
Companies use several different methods for hardness testing, the most common being Brinell, Rockwell, Vickers, Leeb. However, there are disadvantages to each method: for Rockwell and Brinell, testing may lead to damage on the surface of a sample; for Vickers, only professional technicians are able to carry out tests smoothly; and for Leebs, the testing method is indirect, which may lead to a large deviation when converted to other scales.
To study the properties of materials as they change temperature, companies often use a thermal analyzer on product samples. There are many types of thermal analyzers, spanning different properties that can be measured as a sample undergoes various material changes.
An x-ray fluorescence spectrometer is an instrument used for chemically analyzing rocks, minerals, and sediments. As such, it is a highly valuable tool in a number of industries, including precious metal and ornamental processing industries, as well as banks and shops that sell gold and other ornamental metals.
A production line in a manufacturing facility is an extremely hectic, demanding place. There are many small objects and pieces of equipment that must be kept managed and organized to ensure that operations run smoothly and that tools remain close at hand.
Qualitest’s Frazier Air Permeability Tester enables companies to measure the air permeability of a wide range of products including textile materials, paper, air and water filters, foam, and metal screens. These machines use a calibrated venturi nozzle testing method, combined with a wide differential pressure range, to achieve reliable and repeatable testing.
To study metals, laboratory technicians must measure and view the surfaces of material samples using a metallurgical microscope. For capturing such surface images and video, technicians turn to the metallograph.
Qualitest is pleased to introduce the XJP-6A Advanced Inverted Metallurgical Microscope - Metallograph, a table-top reversed model featuring a rotatable precision quadruple nosepiece. Equipped with a polarized light set and halogen 6V20W illumination, the XJP-6A allows for clear crystallographic analysis.
To determine the notch toughness of steel products, laboratory technicians conduct Charpy impact tests. These tests create V and U notches in a material sample to gauge how much energy it absorbs when fractured.
