The Extech Pocket Hygro-Thermo-Anemometer-Light Meter is a 4-in-1 instrument that measures humidity, temperature, air velocity, and light. The ergonomic design with large dual LCD records min/max readings, and the data hold function freezes readings on the screen. The built-in low friction vane wheel improves accuracy of air velocity in ft/min, MPH, m/s, km/h, and knots. The optional type K probe measure temperature to 2372°F (1300°C). The meter utilizes precision photo diode and color correction filter to create cosine and color corrected light measurements.
