Infrared thermocouples and probes

Temperature probes are portable spot-measuring instruments that can be a simple combination of an IR thermocouple and a readout device. They are characterized by a low price (from under 100 to 1,500), pocket portability, and a wide collecting angle. They are battery powered and are generally optically preadjusted for minimum spot size at a short working distance (a 1/4-in. spot at a 3/4-in. working distance is typical). Some models are designed to operate in a conventional 

Probes are ideal for close-up measurements and find applications in circuit board analysis, troubleshooting of electrical connections, inspection of plumbing systems, and a variety of biological and medical studies. Most recently, consumer versions of these devices have emerged forborne use at extremely low prices. One example is an IR ear thermometer to measure body temperature, available at pharmacies for under 25.
