The Extech 42570 Dual Laser Infrared Thermometer is a versatile and accurate instrument for non-contact temperature measurement. This thermometer is designed to provide precise readings, convenient features, and flexibility for a wide range of applications.The Extech 42570 features dual lasers that converge into a single spot at approximately 50 inches from the target. This convergence point enhances accuracy and ensures precise temperature measurement on the intended spot, minimizing errors and increasing measurement confidence.With its fast response time of 100 milliseconds, the thermometer provides rapid temperature readings, allowing for efficient and time-saving measurements. This quick response time is crucial in applications where temperature changes quickly, or when multiple measurements need to be taken in quick succession.The thermometer is equipped with a Type K input, enabling direct measurement of Type K thermocouples. This feature adds versatility and expands the temperature measurement capabilities of the instrument.The USB interface allows for convenient data transfer and connection to a computer. You can easily retrieve temperature data, save it for further analysis, or integrate it into your data management systems using the USB interface. This feature enhances productivity and facilitates efficient data handling.The adjustable emissivity feature increases measurement accuracy on various surfaces. By adjusting the emissivity, you can compensate for differences in how different materials emit infrared energy, ensuring accurate temperature measurements across a variety of surfaces.The adjustable high/low set points with an audible alarm provide an added level of convenience and safety. You can program specific temperature thresholds, and when the measured temperature exceeds these set points, the thermometer alerts you with an audible alarm. This feature allows for proactive monitoring and timely intervention to prevent temperature-related issues.The MAX/MIN/AVG/DIF measurement modes display the highest, lowest, average, and maximum minus minimum temperature values. This comprehensive measurement capability enables better analysis and comparison of temperature variations over time.
