The 3i Series is available in a broad variety of temperature ranges, sighting options, optical ranges, and offers spectral responses to meet the needs of specialized industrial applications. These units are made-to-order and matched for optimum performance when measuring critical temperatures in very distant targets or high temperatures up to 3000ºC or 5400ºF. To assure accuracy, 3i Series also compensates for the energy reflected by the background around the target, making it a great tool to use nearby objects with high temperatures; for example inside a furnace. With Raytek 3i series, you have a choice between single and dual laser models, crossed laser models, and scope sighting models. Advanced applications and processes need specialized tools like the Raytek 3i IR (infrared) thermometer. The Raytek 3i series of noncontact thermometers measures surface temperature in places other thermometers cannot. With a choice of spectral responses, temperature ranges, laser sighting options and on-board data logging capabilities, the Raytek 3i meets the individual requirements of demanding users. Overcome the limitations of contact thermometers in manufacturing plants with Raytek 3i series infrared thermometers. For the most accurate readings in hot environments, the 3i thermometer compensates for the energy reflected by the background around the target. Reflected background energy compensation allows for accurate measurement even when the area measured is reflecting energy from nearby objects with higher temperatures; for example, inside a furnace. Varying spectral responses, laser-sighting systems, and distance-to-measurement spot ratios ensure the Raytek 3i temperature measurements are precise. LT and LR 1M and 2M G5 and P7
