The Extech SDL310 is a high-accuracy vane thermo-anemometer that simultaneously measures air velocity and temperature using a lightweight vane sensor rated for temperatures up to 122°F (50°C) and air speeds up to 4930 ft/min. Designed for HVAC, environmental, and industrial airflow diagnostics, it logs timestamped data directly to a 2 GB SD card in Excel®-compatible CSV format for easy transfer and analysis on a PC. With a user-selectable sampling interval from 1 to 3600 seconds, Type K/J thermocouple inputs for external high-temperature measurements (up to 2372°F / 1300°C), and a 39" (1 m) sensor cable, the SDL310 offers versatile and reliable performance. It includes 6 AA batteries, SD card, vane probe, and hard carrying case.
