EXTECH EN300 5 In 1 Environment Meters

EXTECH EN300 5 In 1 Environment Meters measures Humidity, Temperature, Air Velocity, Light and Sound. The large dual LCD simultaneously displays Temperature and Air Velocity or Relative Humidity. Characters on display reverse direction depending on Hygro-Thermo-Anemometer or Light-Sound mode.

Built-in precision thin-film capacitance humidity sensor for fast response and a thermistor for ambient temperature measurement. It utilizes precision photo diode and correction filter for Cosine and color corrected light measurements. Type K input measures temperature to 2372° (1300°C) using an optional Type K probe. Sound Level measurement meets IEC 61672 class 2.
