Extech infrared thermometers are used to measure surface temperatures up to 1400 degrees F (760 degrees C) with a built-in laser pointer which identifies the target area and improves the aim. These units feature an adjustable high / low audible alarm and an adjustable emissivity function that increases the measurement accuracy on different reflective surfaces. They further come equipped with a lock function for continuous display of readings, a 9 V battery, a carrying case and a user manual.
