Extech 45170 Environmental Meter (Hygro-Thermo-Anemometer-Light Meter) is a rugged 4-in-1 environmental meter that measures humidity, temperature, air velocity and light. This Hygro-Thermo-Anemometer-Light Meter features a built-in low friction vane wheel that improves accuracy of air velocity in ft/min, MPH, m/s, km/h, and Knots.
- 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
- Type K input measures temperature to 2372?é?? (1300?é??C) using optional Type K probe
- Utilizes precision photo diode and color correction filter
- Cosine and color corrected light measurements
- Defaults to last function when powered off
- Auto power off 10 minutes after last key is pressed with disable feature
- Low Battery and overrange indication
- Built-in Humidity sensor, Light sensor and Vane wheel, wrist strap, and 9V battery.
