Extech 42510A Mini Infrared Thermometer -58 to 1200°F 12:1 Laser Pointer NIST

The Extech 42510A-NIST Wide Range Mini Infrared Thermometer is a compact and highly accurate tool for non-contact temperature measurement, tailored for professionals in HVAC, electrical, automotive, and general industrial fields. With a measurement range from -58 to 1200°F (-50 to 650°C), this thermometer delivers precision and reliability for demanding temperature monitoring tasks.

Featuring a high resolution of 0.1° up to 199.9°, the device allows for detailed readings, while adjustable emissivity ensures accurate results across a variety of surfaces. Its built-in laser pointer provides easy target identification, and the 12:1 distance-to-spot ratio makes it ideal for safe distance measurements.

Additional features such as high/low set points with an audible alarm, data hold, Min/Max memory, over-range indication, and a large backlit LCD enhance usability in all lighting conditions. The auto power-off function conserves battery life, and NIST calibration is included for traceable measurement assurance.
