Detu testo 435-1 multifunctional wind speed measuring instrument
Probe suitable for various needs
Indoor air quality probe: The developed indoor air quality probe can measure CO2, relative humidity, and indoor air temperature to evaluate the quality of indoor air. This probe can also measure absolute pressure.
Turbulence probe: The human body is very sensitive to suction force. With the help of the turbulence probe from Detu, an objective evaluation of the blowing sensation caused by indoor air flow velocity can be made.
Elastic surface probe: Elastic surface probes have excellent performance in measuring surface temperature. The elastic surface of the probe better contacts the object being measured, achieving fast and accurate measurements.
Thermal wind speed probe: The new generation of thermal wind speed probe has a built-in temperature and humidity sensor, suitable for measuring ventilation ducts and other objects. In this way, wind speed, air volume, air humidity, and air temperature are all measured in the same process.
Impeller probe: optional 60mm diameter, suitable for integrated measurement at ventilation openings and other locations. For the inspection of ventilation ducts, it is ideal to use a 16mm diameter impeller probe, which has a wide range of 0.6~40m/s.
Pitot tube: Pitot tubes are most suitable for use in high wind speeds and polluted airflow.
Comfortable user interface
The uniqueness of Testo 435 lies in its user-friendly functional design and simple and user-friendly menu operation. For the measurement of pipeline and indoor air quality, testo 435 can be freely switched between different user menus.
User menu - Pipeline measurement
Some key functions of pipeline measurement, such as calculating time periods/multi-point averages and inputting cross-sectional areas, can be directly accessed by pressing the function keys to enter the operation interface. You can choose the type of cross-sectional area on site, such as circular or rectangular. Moreover, the instrument is equipped with 5 preset sizes that users can directly select through the function keys.
User Menu - Indoor Air Quality
The key to detecting indoor air quality is long-term measurement. Users can set and program measurement programs on the testo 435 instrument, freely choose measurement parameters, and record long-term measurement data.
Absolute compact design concept
The reliability of performance is the key to judging the quality of measuring instruments. The waterproof rating of Testo 435 reaches IP 54, which is sturdy, durable, and reliable in performance. The shell is made of special materials and has the function of shock and impact resistance. The spacious backlit display screen is embedded in the casing and is not easily damaged. The instrument is also equipped with a strap design for easy transportation and carrying. The magnet on the back of the instrument is convenient for fixing and placing the instrument during measurement.
Reliable measurement data management
The Testo 435 is equipped with powerful measurement data processing capabilities, allowing for on-site printing of measurement reports using a portable Detu printer. Can print measurement time and location simultaneously.
The Testo 435-1 has a loop printing function. Press the "Loop Printing" function button to cycle the printing of data on the Detu printer with a printing cycle of 1 minute to 24 hours. In this way, the series of measurement tasks can be directly printed out without the need for further storage.
