5-in-1 Environmental Meter

  • 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 measurementmeets IEC 61672 class 2.
