Extech Hygro Thermometer Anemometers Light Meter

4-in-1 meter measures humidity, temperature, air velocity and light. Dual LCD simultaneously displays temperature and air velocity or relative humidity. High temperature air or surface measurements can be made using the built-in type K input. Comes complete with built-in humidity sensor, light sensor and vane wheel, wrist strap, and 9v battery.

Ergonomic pocket size housing with large dual LCD simultaneous display of temperature and air velocity or relative humidity Data hold to freeze the displayed value Records minimum/maximum readings Built-in low friction vane wheel improves accuracy of air velocity in ft/min, MPH, m/s, km/h, and knots Built-in precision thin-film capacitance humidity sensor for fast response High temperature measurements using type K thermocouple
