Functions

A moisture analyzer is a device used to measure the moisture content in both high level and trace amounts in solids, liquids, or gases. It is necessary information to know in commercial food production, and trace moisture measurement are necessary for manufacturing and process quality assurance. As the name suggests, density meters measure the density of a sample and it is typically either has the units of kg/m3 or lb/ft3. Density can be calculated as p=m/V, where p is the density of the sample, m is the mass, and V is the volume. Many density meters can measure both the wet and dry portion of the sample, but this density meter can solely measure the dry solids present in the sample. Spectrophotometers are commonly used for the measurement of wavelengths intensity in a spectrum of light compared with the light intensity from a standard source. In other words, it measures the brightness of the various portions of spectra.

Moreover, GAOTek insulation resistance testers provide noise-free and reliable results with perfect solution for troubleshooting, commissioning, and preventative maintenance applications. A megohmmeter (also called insulation resistance testers, teraohmmeter) is used to measure the ohmic value of an insulator under a direct voltage with a high stability. It is ideal for working on motors, generators, cables, and switch gear. Concrete rebar detectors are designed to meet the required need of the construction and building industry to provide both visual and acoustic indication that lies beneath the concrete surface. Additionally, the detectors will locate, size, and show bar orientation, as well as indicate concrete cover.

Impact testers are one of the most important properties for component designers to consider for critically measuring the service life, safety, and liability of a product. The impact tests are highly difficult to quantify, thus these devices excellent to precisely determine the absorbed impact energy and resistance to breakage. Lastly, a spectrometer is an instrument used in the study of physics, astronomy, and chemistry to split light into an array of separate colors called a spectrum. It can also determine the chemical composition of stars and planets to gather information about the origin of the universe.
