CUSTOM Data Logger Anemometer WS-03SD

An anemometer that can also record data to an SD card.

• It is possible to measure wind speed and ambient temperature using the temperature sensor in the wind speed sensor section. Temperature can also be measured using separately sold K-type and J-type thermocouple sensors.
• The anemometer uses a hot wire method, which is convenient for measuring minute wind speeds. The sensor probe is extendable, making it convenient for measuring at high altitudes.
• The recorded data can be used with commercially available spreadsheet software, making it suitable for a variety of purposes.
• Data recording can be selected from automatic recording or manual recording.
• The sampling time for the automatic data logger can be set to any of the following: 1, 2, 5, 10, 30, 60, 120, 300, 600, 1800, or 3600 seconds.
• Comes with a green backlight function that makes it easy to see even in dark places.
• Equipped with a hold function that temporarily freezes the measurement value on the display.
• Comes with a MAX (maximum value)/MIN (minimum value) display function for measurement values.
• To prevent battery drain, the device is equipped with an auto power off function that automatically turns off the power if the device is not operated for a certain period of time.

Measurement results can be recorded by inserting an SD card.

The data recorded on the SD card can be imported into spreadsheet software such as Excel as a CSV file.

• The above measurement accuracy does not include the accuracy of optional sensors.
• We do not carry J-type thermocouple sensors.
• Using the sensor for purposes other than its intended use or handling it roughly may result in damage to the sensor or injury, so please select a sensor that is suitable for your purpose.
• Depending on the object being measured and how it is used, the sensor may be damaged.
• Please use the sensor within a temperature range with sufficient margin.
