SAR 3 764
  • Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow, air temperature and humidity
  • Precise: accurate measurement results from 0 to +50 m/s and automatic absolute pressure compensation
  • Convenient: probe with a practical button on the handle for storing individual readings, convenient measurement in any cross-section with scaled telescope (up to 1 m), optionally extendable to 2.0 m
  • Intelligent calibration concept
  • For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow, air temperature and humidity.
    Use the hot wire probe with the compatible testo multifunction measuring instrument (please order separately) to determine air velocity, volume flow, air temperature and humidity.

     

    Hot wire probe including temperature and humidity sensor – features

    Use the fixed cable on the handle to connect the hot wire probe to the measuring instrument (please order separately). The hot wire probe is equipped with a telescope, which can be extended to a maximum length of 1.0 m. The immersion depth is easy to read, even if visibility is poor, thanks to 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.

    Particularly useful: press the button on the hot wire probe to operate the measuring instrument. For example, to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time.

    Integrated sensor protection: when you are not using the hot wire probe, the rotatable protective cap protects the air velocity sensor from mechanical stress.

     

    Space-saving: more applications, less equipment

    Endlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space.

    Order the Bluetooth® handle to make it more convenient to carry out your measurement and guarantee less cable clutter in the case. This transmits the readings to the measuring instrument from a distance of up to 20 metres. If the sensors (air velocity, temperature, humidity) need to be replaced in the distant future, you can change the probe head.

    If required, you can also fit the hot wire probe with the telescope extension (available to order separately). You can therefore attain a total length of 2 metres, making it easy to carry out measurements on large ventilation systems.

     

    Intelligent calibration concept

    You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.

     

    Areas of application for the hot wire probe

    Ventilation ducts: Use the hot wire probe to measure flow velocity, air temperature and humidity in ventilation ducts with reliability.
    Since the measuring range goes up to +50 m/s and the total length of the probe can be extended to 2.0 m (please order the telescope extension separately), measurements can even be carried out on large ventilation systems.
