Optical Sorting Machine

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.

To help manufacturers organize small metallic objects on production lines, such as screws, rivets, and bolts, Qualitest offers its line of optical sorting machines. Designed to accommodate flexibility over a wide range of parameters, Qualitest’s optical sorting machines can measure and recognize very specific features of objects including hardness, thread numbers, heat treatment, surface defects, and many more.

Qualitest’s optical sorting machines have user-friendly interfaces and save valuable time for manufacturers. Equipped with high quality cameras, these powerful machines are the most cost-effective solution for maintaining order and increasing efficiency on production lines.

Frazier 2000 Differential Pressure Air Permeability Tester

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.

Qualitest offers a variety of air permeability models, ranging from the cost-effective manually operated units, to the more sophisticated automated models. All models are very accurate, conducting tests that are repeatable to within +/-2%, and maintain their calibration over long periods of time without maintenance. 

Table-top Reversed Metallurgical Microscope

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.

With a binocular head and separate photo tube for photography and video, a large mechanical stage (7x6 inch), and co-axial coarse and fine line focus control, the XJP-6A provides ideal conditions for measuring, viewing, and studying material samples.

Charpy Specimen Machine – CNM

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.

Qualitest offers a state-of-the-art Charpy Specimen Machine, which enables technicians to produce 10mm square Charpy test specimens independently, without waiting for machine shop time. Capable of machining up to four samples at once, Qualitest’s Charpy Specimen Machine works on samples up to 16mm square, using a five-blade cutter with easily replaceable inserts.

Metallography Polisher - QualiPol-Auto - Automatic Polishing Machine

Polishing metals for industrial applications is about more than just appearance: this process is necessary to prevent corrosion and oxidation of metal products, which improves their lifespan and durability. Metallography polishers are sophisticated machines that are used to polish metal samples in order to establish standards that can be applied on an industrial scale.

Qualitest offers a complete and competitive range of metallography polishers, available in a wide variety of configurations (Basic Manual Wheels, Semi Automatic, and Fully Automatic) to meet all industry requirements.

Air Permeability Tester for Cement

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.

The sleek design of our QualiPERM Blaine Air Permeability Testers for Cement and Powders allows for the testing units to be placed conveniently atop any bench within your facility. Qualitest’s family of QualiPERM Blaine Air Permeability Testers are available with manual (QualiPerm I), semi-automatic (QualiPerm II, III, & IV), or fully automatic air pumps (QualiPerm V), and varying numbers of load cells to increase testing capacity.

Leeb Portable Rebound Hardness Tester - QualiTip - Portable Hardness Tester

Qualitest provides many companies with its state-of-the-art hardness testers, but none are as portable and convenient as our Leeb Portable Rebound Hardness Tester, known as the QualiTip. This hardness tester is specialized to enable examination of large and heavy objects on production lines of mass-produced components, and in restricted spaces that would otherwise be difficult to access.

Vicat Needle Apparatus - QualiSET

The Vicat test is used by industry for testing materials that have no real melting points, such as cement and mortar. The Vicat test is conducted by measuring the temperature at which a flat-ended needle is able to penetrate the sample, which is known as the “softening point” of the material.

Qualitest’s automatic Vicat Tester has unmatched precision and accuracy, applying force to the sample while also recording the depth of the needle. This Vicat Tester also reduces the time requirements for tests by performing the same test 6 times simultaneously.

Spectroscopy Instruments

Qualitest’s Spectrophotometer is an instrument that accurately measures the amount of light that passes through a material. By customizing the wavelength of the light emitted by the Spectrophotometer, operators in both industry and laboratory environments can use this instrument to determine the exact concentration of certain chemicals in material samples. This enables companies to ascertain the precise composition of materials used in their products.

With an auto-ignition feature and automatic spectral bandwidth selection, Qualitest’s Spectrophotometer is a sophisticated machine that is surprisingly easy to use. The Spectrophotometer’s light-controlled graphite furnace ensures fast heating, accurate and stable temperature control, and dependably reproducible results.

Portable Surface Roughness Tester - QualiSurf I

Surface texture tests are essential for manufacturers to determine how a product or material will interact with its environment. Certain degrees of roughness can be both a positive and negative feature for a material: it can be used to facilitate adhesion in certain applications, but roughness can also instigate cracks or corrosion.

Qualitest is pleased to introduce its QualiSurf I portable surface roughness tester, which is a pocket-sized instrument for measuring surface texture. Conforming to traceable standards that are recognized around the world, the QualiSurf I can be used on various surfaces in any position — horizontal, vertical, and anywhere in between.
