The Extech 42570 is a high-performance infrared thermometer designed for extreme-temperature industrial applications. Featuring a wide non-contact range up to 3992°F (2200°C), a 50:1 distance-to-spot ratio, and dual-laser targeting that converges at 50" to indicate the exact 1" measurement area, it ensures precision on small or distant targets. It also includes a Type K thermocouple input for contact measurements, USB data logging with PC software, and adjustable Hi/Lo audible alarms — making it ideal for metalworking, glass manufacturing, and predictive maintenance.
