Extech 45170 Hygro Thermo Anemometer Light Meter

It's 4 meter in one! Use Extech's 45170 to test humidity, air temperature, air velocity and light levels.

Pocket-sized, easy-to-use and capable of generating reliable, accurate results, Extech's 45170 is an excellent solution for testing several environment parameters without the need to switch between instruments. All the sensors are built directly into the instrument - it includes a precision thin-film fast response humidity sensor, a built-in thermistor sensor for ambient temperature measurements, a precision photo diode sensor for light measurements and a low-friction vane wheel for measuring air velocity.

With this instrument, you'll be able to test all of the following:

• Air velocity in ft/min from 80 to 5910ft/min
• Air velocity in m/s from 0.4 to 30m/s
• Air velocity in km/h from 1.4 to 108km/h
• Air velocity in MPH from 0.9 to 67MPH
• Air velocity in knots from 0.8 to 58.3 knots
• Light in Foot Candles from 0 to 1860FC
• Light in Lux from 0 to 20,000Lux
• Ambient air temperature in Celsius/Fahrenheit from 0 to 50°C (32 to 122°F)
• Relative humidity from 10 to 95% RH

The Extech 45170 can also be combined together with an optional type K temperature probe to measure temperature in a wide variety of other applications.

Additional features of the Extech 45170 includes a data hold function, the ability to record MAX/MIN readings, automatic power off and a rotating LCD screen (depending on which measurement mode is being used).
