ترمومتر لیزری فلوک مدل FLUKE 572

The Fluke 572 precision infrared (IR) thermometer measures surface temperatures to locate lubrication problems, overloads, short-circuits, or misaligned and overheated equipment. The thermometer has a -25 to +1,600 degrees F/-30 to +900 degrees C measuring range. The extra-bright 635nm laser clearly highlights the targeted area. The coaxial three-dot laser sighting system highlights the true diameter of measurement spots at all distances (90% energy). Enhanced optics have a D:S (distance-to-spot) ratio up to 60:1 and a minimum measurement diameter of 0.76″/19 mm at a standard focus distance of 3.8’/1.15 m, for measuring small diameter objects at a distance. The 50:1 D:S ratio has a minimum measurement diameter of 0.25″/6 mm at a close focus of 0.98’/0.3 m for specialized applications. Emissivity can be adjusted in 0.01 increments for more accurate measurements. The backlit display eases reading in poorly lit areas. The thermometer automatically calculates minimum and maximum measurements, and a user-settable high temperature alarm provides instant audible and visual notification. The last ten temperature readings can be displayed on a bar graph for reference. The pistol-grip handle eases targeting over long distances and a 1/4″-20 UNC (unified coarse) tripod mount stabilizes the thermometer for longer measurements. The thermometer is powered by two AA alkaline batteries (included) and includes a hard-sided carrying case and instructions.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Digital thermometers are instruments used to measure the temperature of air, liquids, or surfaces electronically. They may measure temperature in Celsius, Fahrenheit, or both. Most digital thermometers use thermistors, which are small electronic resistors. Thermistors are made out of metals that conduct electricity within a certain range and become more conductive the warmer they get. A microcontroller inside the thermometer measures this electrical conductivity and converts it to a temperature, which is displayed on an LCD. Digital thermometers are used in a wide range of applications, including in laboratory settings, food service and storage, and in doctors’ offices and hospitals.
