- Measuring range from 118 to 9842.5 fpm with accuracy of up to ±(39.37 fpm + 1% of m.v.)
- Integrated telescope with scaling extends up to 39.4 in. (1 m), making it easy to carry out measurements in ducts
- Fixed cable on handle easily connects probe to measuring instrument
- Pressing button on handle allows individual readings to be stored directly in the measuring instrument
- Universal handle can easily be connected to other probe heads
- Intelligent calibration concept allows main unit to be used continuously, with only the probe head requiring calibration
- Includes temperature sensor
The Testo 0635 9572 Digital Vane Probe, 16 mm, with Fixed Cable is used to measure air velocity, volume flow, and air temperature. The fixed cable on the handle is used to connect the vane probe to a measuring instrument (sold separately). The vane probe is equipped with a telescope, which can be extended to a maximum length of 39.4 inches (1 m). The telescope's immersion depth is easy to read, even if visibility is poor, because of the high-contrast scaling.
The clearly structured measurement menu for volume flow enables the measuring instrument to be operated intuitively. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.
Individual readings store directly in the measuring instrument by pressing the button on the vane probe. For example, users can store individual readings for multi-point mean calculation or start and stop measurement series for mean calculation over time.
Wireless and Space-Saving: More Applications, Less Equipment
The universal handle can be connected to all probe heads - so you can master more applications using less equipment and save space. A Bluetooth handle (sold separately) makes it more convenient to carry out your measurements and guarantees less cable clutter; the handle transmits readings to a measuring instrument from a distance of up to 65 feet. If the vane needs to be replaced in the distant future, you can change the probe head.
If required, you can also fit the vane probe with a telescope extension (sold separately). Doing so allows you to attain a total length of 6.56 feet (2 m), making it easy to carry out measurements on large ventilation systems.
Intelligent Calibration Concept
Users receive exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. Only the probe head needs to be sent in for calibration - allowing the measuring instrument to remain in continuous use.
Areas of Application for the Vane Probe
Ventilation ducts: Use the vane probe to reliably measure air velocity and air temperature, even at locations that are difficult to access in ventilation ducts. If required, the total length of the probe can be extended up to 6.56 feet (telescope extension sold separately), making it possible to carry out measurements on large ventilation systems.
Plate outlets and ventilation grilles: For convenient, accurate measurements at plate outlets and ventilation grilles, use the vane probe in conjunction with the testovent 410 or testovent 415 funnel (sold separately). This makes it easy to test the exhaust air - such as in the controlled ventilation of living spaces.
