| Property Analyzed: | |||
| Your choices are... | |||
| Permeability - Gas / Vapor | Gas or vapor permeability is a measurement of a sample’s ability to transmit gases or vapors. The oxygen transmission rate (OTR) and the water vapor transmission rate (WVTr) are important measurements in determining the ability of a packaging film or material to maintain freshness. | ||
| Permeability - Liquid | Liquid permeability measures a sample's ability to transmit liquids. | ||

Test Media / Material
Back to Top
|
|
| ||
| Your choices are... | |||
| Adhesives / Coatings | Devices test substances that coat, fasten, bond, or seal materials. Adhesives that bond and seal are called adhesive sealants. Coatings are thin layers of protective or decorative compounds that are bonded to the surface of a substrate by a variety of methods. Wetting and surface energy are key properties in the processing and function of coatings, adhesives, and sealants. | ||
| Asphalt / Pavement | Devices are designed to evaluate the properties of asphalt or other types of pavement materials. | ||
| Building & Construction Materials | Devices are designed to evaluate building and construction materials such as metal, plastic, rubber, asphalt, concrete, cement, mortar, adhesives, sealants, rock or aggregate, soil, wood , textiles, and foam. | ||
| Ceramics / Glass | Ceramics consist of oxides, carbides, nitrides, carbon, and other non-metals with high melting points. Ceramics are suitable for applications requiring wear resistance, refractoriness, low electrical resistivity, or other specialized characteristics. | ||
| Chemicals | Devices test liquid, gas, powders, or solid substances that have a distinct molecular composition and are produced by a chemical process. | ||
| Concrete / Cement | Devices are designed to evaluate the properties or workability of concrete, mortar, or cement products. Concrete is a mixture of Portland cement, water, and aggregate. Mortar contains these same ingredients along with hydrated lime and sand to facilitate workability and decrease working time. | ||
| Food / Drugs | Devices are designed to test food, drugs, drug additives, food additives, beverages, pharmaceutical materials, active pharmaceutical ingredients (APIs), or food ingredients for properties such as contamination, flow, texture, stability, melting point, freezing point, foamability, dissolution, or water absorption. | ||
| Fuel | Devices are designed to test traditional fuels like petroleum and fossil fuels, renewables like biomass and biofuels, and emerging technologies including hydrogen and nuclear materials, for properties including energy density, blend composition, and octane / cetane level. | ||
| Gases | Devices are designed to test gases such as argon, carbon dioxide, phosphine, nitrogen, oxygen, mixed gases, propane, natural gas, semiconductor gases, medical gases or process gases, and other specialty gases. | ||
| Geological (Rock, Strata, etc.) | Devices are designed to test or perform geophysical analysis on geological materials such as rock, stone, soil, strata, etc. Such test equipment is used to provide tests in the field, core or extract specimens (sampling), or provide laboratory analysis on samples (cores, specimens) taken from the field. | ||
| Metals | Devices are designed to test metals or alloys with two or more metallic elements. As a category, metals include electropositive elements that are generally good conductors of heat and electricity, and that can be melted or fused, hammered into thin sheets, or drawn into wires. | ||
| Oils / Lubricants | Devices are designed to test greases, oils, lubrication oils, solid lubricants, distillates, or other petroleum products. | ||
| Packaging Materials | Devices are designed to test packaging materials, which include films, tapes, bags, and containers of plastic, elastomer, glass, or foam compositions. | ||
| Polymers (Plastics, Elastomers) | Devices are designed to test polymers, plastics, and elastomers. Polymers are organic, synthetic, or processed materials typically consist of thermoplastic or thermosetting resins. Plastic testers or test equipment tests any of various organic compounds produced by polymerization. These materials can be molded, cast, or extruded into various shapes and films. Rubbers and elastomers are polymers that exhibit very high elasticity and resilience compared to plastic polymeric materials. | ||
| Porous Materials (Filters, Foam, etc.) | Devices test foam, filters, filtration media, and other porous materials. | ||
| Powders / Granular Materials | Powders and granular materials are finely divided forms of metals, ceramics, polymers, composites, minerals, or other raw materials. | ||
| Pulp / Paper | Paper is made of cellulose pulp and derived mainly from wood. | ||
| Rock / Aggregate | Devices can be used to evaluate rock, stone, crushed ore, or aggregate in the field, or to test a sample removed from the field. Minerals and ores are raw materials that are crushed, milled, extracted, refined and/or processed to produce finished products such as glass, fillers, reinforcements, cement, metals and ceramics. | ||
| Soil | Soil, the top layer of the earth's surface, consists of rock and mineral particles mixed with organic matter. | ||
| Textiles | Devices are designed to test woven or non-woven textiles, cloth, or other fiber-based materials. | ||
| Wood / Wood Product | Devices are designed to test the properties of wood or wood products such as timber, lumber, plywood, engineered wood products, particle board, wood flour, and other wood-based materials. | ||
| Other | Other unlisted, specialized, or proprietary media. | ||

| Display & Special Features | |||
| Your choices are... | |||
| Analog Meter | Data is displayed with an analog meter or simple visual indicator. | ||
| Computer Interface / Networkable | The instrument can be connected to a network or personal computer for the transfer of data or test control. | ||
| Digital Readout | Device uses numerical or application-specific displays. | ||
| Graphic / Video Display | The data is presented in video form with a cathode ray tube (CRT), liquid crystal display (LCD), or other multi-line form. | ||
| Handheld / Field | Handheld or portable devices are used in field applications to test soil, construction materials, and pavement. | ||
| Laboratory / Batch | Devices are benchtop, table-based, or floor-mounted gages or instruments where a part is both manually loaded and measured. The tester, instrument, or test equipment is a larger, free-standing or floor-mounted unit. | ||
| Process Line Mounted (Continuous) | Sensors, instruments or monitors are mounted within or on a process line, piece of equipment, or machine tool in a production environment to allow continuous monitoring and control of specific materials or media properties. | ||
| SPC Software / Capability | Instruments have integral or optional SPC software or analysis capability. | ||
| Other | Other unlisted display option types. | ||
