Three models of infrared (IR) thermometers feature pistol grips for easy handling and a single-dot laser sighting system for accurate aiming, the company states. IR thermometers 63, 66, and 68 have an intuitive user interface and single-trigger activation. When the trigger is depressed and held down, the laser illuminates; temperature readings are updated continuously and displayed on the backlit LCD screen. Models 66 and 68 feature 12-point data logging and selectable MAX, MIN, DIF, and AVG functions designed to display values instantly with a high-low alarm. The thermometers are built to withstand harsh field use, the company says. All three models come with carrying case and tripod mounting.
