1. Product Introduction
Thank you for purchasing this Anemometer.
The Anemometer is an air velocity and
temperature of air measuring instrument. To
measure an air velocity, put sensor head face to
the air velocity value.
1-1 Features
Combination of hot wire and standard
thermister, deliver rapid and precise
measurement event at low air velocity.
Wide range measurement of air velocity,
fast response time.
Multi-function for air velocity measurement:
m/s, km/h, ft/min, mile/h.
Super large LCD with dual function display,
read the air velocity & temperature at the
same time.
Data hold and record / recall maximum,
minimum, and average reading.
Ultra low power consumption in shutdown
mode.
Auto power off after 10 Minutes of idle.

2-2 Safety symbols
Dangerous, refer to this manual before using
the meter.
CE Certification
This instrument conforms to the following standards:
En61326: Electrical equipment for measurement,
control and laboratory use.
IEC61000-4-2: Electrostatic discharge immunity test.
IEC61000-4-3: Radiated, radio-frequency,
electromagnetic field immunity test.
IEC61000-4-8: Power frequency magnetic field
immunity test.
Tests were conducted using a frequency range of
80-1000 MHZ with the instrument in there orientations.
The average error for the three orientations is ±0.5°C
(±1.0°F) at 3V/m throughout the spectrum. However,
between 781-1000MHZ at 3V/m, the instrument may
not meet its stated accuracy.
Restrict to use of six substances within
electrical and electronic equipment (EEE), thereby
contribution to the protection of human health and the
environment.
The device may not be disposed in trash. It
promotes the re-use recycling and other forms of
recovery of used materials and component, and to
improve the environmental performance of all
operators (manufacturers, traders and treatment
facilities) involved in the life cycle of products. Dispose
of the product appropriately in accordance with the
regulations in force in your country.
The device of used materials content no
substances that list of proposed REACH substances of
very high concern.

4-3 Battery Placement
The meter is powered by a 9V battery. When
symbol appear, the battery voltage drops below the
level for reliable operation, the user has to replace a
new battery. To change the battery, open the battery
cover on the back and replace the battery in the battery
compartment. Make sure the cover is well snapped
after the replacement of battery.
4-4 AC Power
Except battery power supply, the unit also consumes
AC power via USB cable: Plug the AC adapter to the
wall jack Option.

4-5 Sensor Tip Description
• Sensor Head:
○1 Air Direction Arrow
○2 Air Velocity Sensor
(Do not touch!)
○3 Temperature Sensor
To protect the sensors,
please telescope the
sensor head into the
wand when the meter is
not in use.
Air Velocity Measurement:
Place the sensor in the air current to be measured.
Have the air flow meet the sensor head in the direction
toward the arrow.
Warning! Do not touch the air velocity or
temperature thermistor inside the sensor
head.
