Extech SDL300 Anemometer/Data Logger

The SDL300 uses a robust metal vane probe to capture air velocity up to 6,900 ft/min (~35 m/s) while enduring ambient temperatures up to 158 °F (70 °C). Simultaneously, it monitors air temperature, displaying both measurements on a large dual LCD display. Its built-in datalogger saves readings to an SD card in Excel-compatible format, with adjustable sampling intervals from 1 to 3,600 seconds. For manual capture, it can record up to 99 readings internally. The device includes a Type K/J thermocouple input, allowing it to measure higher temperature sources beyond typical ambient range. Functional features like MIN/MAX recording, data hold, and auto power-off (with disable option) add convenience. The vane is connected by a 1 m cable, and the instrument supports multiple velocity units (ft/min, m/s, mph, km/h, knots). The SDL300 comes complete with batteries, SD card, carrying case, and PC interface for data transfer.
