Extech 45170 4-in-1 Environmental Meter

Pocket-size rugged meter for Humidity, Temperature, Air Velocity and Light

This 4-in-1 meter measures Humidity, Temperature, Air Velocity and Light. The dual LCD simultaneously displays Temperature and Air Velocity or Relative Humidity. High Temperature air or surface measurements can be made using the built-in Type K input. Comes complete with built-in Humidity sensor, Light sensor and Vane wheel, wrist strap, and 9-Volt battery.

4-in-1 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
