The non-contact Extech 42545 infrared thermometer is equipped with a backlit illuminated display for taking measurements at night or in areas with low background light levels. With a 50:1 distance to target ratio, the Extech 42545 infrared thermometer measures smaller surface areas at greater distances.
The high temperature Extech 42545 infrared thermometer has a temperature range of -58 to 1832°F (-50 to 1000°C). Non-contact temperature measurements are available at the touch of a button with the Extech 42545 infrared thermometer. The built-in laser pointer increases target accuracy while the handy pushbuttons provide convenient, ergonomic operation. The Extech 42545 infrared thermometer features a fixed 0.95 emissivity, which covers 90% of surface applications.
The Extech 42545 infrared thermometer has many applications. Use your Extech 42545 infrared thermometer to measure surface temperature of objects which are difficult to reach or unsafe to contact and to measure hot spots in electrical panels and equipment. You can also use your Extech 42545 infrared thermometer for in-process temperature measurements.
Infrared thermometers measure temperature from a distance by detecting the amount of thermal electromagnetic radiation emitted from the object being measured. This allows users to accurately measure surface temperatures in hazardous or hard-to-reach places, or other situations in which non-contact temperature measurement is desirable. Infrared thermometer technology is useful in a wide range of applications – including industrial, laboratory, food service, fire fighting, hobby, and home use.
While the technology is relatively simple, the myriad of names given to these devices can be confusing. "Laser Thermometers" makes reference to the laser that helps aim the thermometer. "IR Sensors" and "IR Thermometers" make use of a common abbreviation for "infrared". "Non-Contact Thermometers" is descriptive of the device's ability to measure temperature from a distance. "Radiation Pyrometers" is a scientific/technical term for these devices.
