Extech Instruments has announced the 42570, a dual-laser infrared thermometer that features 100-ms response time and displays highest, lowest, average, maximum and minimum values. Adjustable emissivity increases measurement accuracy for various surfaces, and an alarm alerts the user when the temperature exceeds the programmed and adjustable high/low set point. Ideal measuring distance is indicated when the two laser points converge to a single target spot. Distance to target ratio is 50:1. A lock function is available for continuous readings and data transfer to a PC via the included USB cable and software. A white backlight multifunction LCD with a bar graph provides easy viewing of the Type K temperature probe, which features thermo-couple input ranges from –50 to 1370 °C.
