Extech EN300 Environmental Meter

The Extech EN300 Environmental Meter has a Large dual LCD simultaneous display of Temperature and Air Velocity or Relative Humidity. Characters on the display reverse direction depending on Hygro-Thermo-Anemometer or Light-Sound Mode. The EN300 has a built-in low friction vane wheel that improves accuracy of air velocity in ft/min, MPH, m/s, km/h, and Knots. It also has a built-in precision thin-film capacitance humidity sensor for fast response and thermistor for ambient temperature measurements.
