From Raytek Corporation
Infrared Thermometry (IR) is being used extensively in a variety of manufacturing facilities and power plants to detect energy losses and monitor temperatures of motors, other equipment, and processes. Simple “point and shoot” models make this technology easy to use. A major advantage of this technology is that measurements can be taken instantly and safely from a distance without having to touch hot, hazardous, or moving objects or to access hard-to-reach surfaces. There are three basic methods of using a portable IR thermometer: spot measuring, scanning, and determining temperature differentials. Spot measuring determines the absolute surface temperature of an object, while scanning identifies hot spots as the thermometer is moved along the selected target. The temperature-differential method compares two or more separate spot measurements, either in different locations or at the same location over time. Products & Services
Industrial thermometers are basic bulb style thermometers designed for use in many industrial applications. Traditional liquid-in-glass design is typically used due to low cost and ease of use.
Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. Traditional liquid-in-glass design offers ease of use and low cost.
Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. These devices display temperatures in Fahrenheit, Celsius, or both.
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
Fiber optic light guides are bundles of optical fibers used for the controlled deliver of light. They tend to be more rigid, and transmit well in both the visible and near-infrared (near-IR) regions of the electromagnetic spectrum.
