Extech IR201 Infrared Thermometer

The wide range Extech IR201 infrared thermometer is equipped with a built-in laser pointer to improve aim. With a temperature range of -58 to 518°F (-50 to 270°C), use the Extech IR201 infrared thermometer to measure the surface temperature of objects which are difficult to reach or unsafe to contact. The Extech IR201 infrared thermometer can also be used for in-process temperature measurements or to measure hot spots in electrical panels and equipment.

The pocket-sized Extech IR201 infrared thermometer has a fixed emissivity of 0.95, which covers 90% of surface applications. In addition, the Extech IR201 infrared thermometer has a distance to spot ratio (D:S) of 6:1.

Infrared Temperature Measurement - Technology Explained:

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.
