The Extech 45170 pocket hygro-thermo-anemometer-light meter is a rugged 4-in-1 meter that measures
humidity, temperature, air velocity, and light. The ergonomic pocket-sized housing features a large,
dual LCD with simultaneous display of temperature and air velocity or relative humidity. The Extech
45170 pocket hygro-thermo-anemometer-light meter has many features including data hold to freeze the
displayed value and recording min/max reading.
The Extech 45170 pocket hygro-thermo-anemometer-light meter has multiple built-in features including
a low friction vane wheel which improves the accuracy of air velocity readings in ft/min, MPH, m/s,
km/h, and knots. The built-in precision thin-film capacitance humidity sensor allows for fast
response time, and the built-in thermistor allows for ambient temperature measurements. The Extech
45170 pocket hygro-thermo-anemometer-light meter can take high temperature measurements using a
Type K thermocouple. The Extech 45170 takes cosine and color corrected light measurements.
Power features of the Extech 45170 pocket hygro-thermo-anemometer-light meter include an auto power off
after 10 minutes of non-use. This feature can also be disabled. The Extech 45170 pocket
hygro-thermo-anemometer-light meter also has a low battery and overrange indication function.
