This Dual Laser Infrared Thermometer measures the IR temperature where the dual lasers converge into a single spot around 50 inches from the target. The meter has a quick 100 millisecond response time, a Type K input, and a USB interface. Adjustable emissivity improves measurement accuracy for a wide range of surfaces. Adjustable high/low set points with an audible alarm notify you when the temperature exceeds the programmed set points. The MAX/MIN/AVG/DIF measurements show the highest, lowest, average, and MAX minus MIN values. Includes Type K temperature probe, USB cord and software, carrying case, and 9-volt battery.
