EXTECH 45170 Environmental Meter

Features: Ergonomic pocket size housing with large dual LCD simultaneous display of Temperature and Air Velocity or Relative Humidity Characters on display reverse direction depending on Hygro-Thermo-Anemometer or Light Mode Data Hold to freeze the displayed value Records Min/ Max 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 Built in thermistor for ambient temperature measurements High temperature measurements using Type K thermocouple Utilizes precision photo diode and color correction filter Cosine and color corrected light measurements Auto power off, Low Battery and overrange indication Complete with built-in Humidity sensor, Light sensor and Vane wheel, wrist strap, and 9V battery 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. Includes: Meter Humidity sensor Light sensor Vane wheel Wrist strap
