The Extech 42545 High Temperature IR Thermometer is a powerful instrument designed for accurate and reliable non-contact temperature measurement in high-temperature applications. This thermometer offers advanced features that ensure precise targeting, safety, and convenience.The Extech 42545 is capable of measuring temperatures up to 1832 degrees Fahrenheit (1000 degrees Celsius). This wide temperature range allows for versatile measurement in various industrial, commercial, and residential applications where high temperatures are involved.The thermometer features a high 50 to 1 distance-to-target ratio, enabling measurements of smaller surface areas at greater distances. This feature ensures safe and accurate readings, particularly when measuring high temperatures from a safe distance. The laser pointer further aids in precisely identifying the target area for accurate temperature measurement.Equipped with a large backlit LCD display, the thermometer provides clear visibility of temperature readings even in low-light conditions. This allows for easy reading and monitoring of temperature measurements, enhancing convenience and accuracy.The adjustable emissivity feature enables the thermometer to provide accurate measurements on different surfaces. Emissivity is the measure of an object's ability to emit infrared energy, and adjusting it allows for precise temperature readings on various materials or surfaces.
