A professional non-contact thermometer with dual laser pointers to provide fast, easy and accurate readings of most surface temperatures between -50°C to 1650°C The impressive 30:1 distance to spot ratio measures smaller surface areas at greater distances, with a 1% accuracy and a rapid 150ms sampling time. Features include automatic data hold & trigger lock, min, max, difference, average temperature displays, high/low alarms, and digitally adjustable emissivity (0.1 to 1.0) for more accurate readings of different materials. Provision for a K-Type thermocouple (supplied) enables you to take direct measurements up to 1370°C, and a USB port lets you transmit the data to a PC for further analysis. Supplied with a tripod, K-type probe, USB cable and carry case.
