Measure air velocity and air temperature with the R4500SD Data Logging Hot Wire Thermo-Anemometer
Anemometers measure wind speed and are important tools for environmental specialists, who study the way air moves. The R4500SD is a real-time data logging thermo-anemometer with an integrated SD memory card that both measures and records air velocity, air temperature, and contact temperature with an integrated Type J/Type K thermocouple input.
This hot wire thermo-anemometer features a thermistor sensor for fast air temperature readings and a hot wire probe for precise low air velocity measurements to save you both time & money. Check out 0:35 in the video to see the many measurements it’s capable of recording.
Record data, save it on an SD card and quickly generate an Excel file – See 1:01.
1. Insert memory card
2. Record the needed data
3. Insert memory card in PC and open with Excel
