This manual introduces the use of the Model 42515 infrared thermometer, including safety precautions, meter appearance, infrared measurement, contact measurement, troubleshooting and other content.
The Extech Model 42515 is a wide-range infrared thermometer designed for non-contact temperature measurements up to 800°C (1472°F) and contact measurements via a Type K thermocouple up to 1370°C (2498°F). It features a built-in laser pointer, adjustable emissivity from 0.10 to 1.00, and an automatic emissivity adjustment function for surfaces above 100°C. The device includes a backlit LCD, alarm settings for high and low temperatures, and a field of view ratio of approximately 13:1.
