Part No. 0635 1032
- Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature
- Precise: automatic absolute pressure compensation guarantees accurate measurement results
- Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in any cross-section
- Intelligent calibration concept
For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow and air temperature.
Use the hot wire probe with the compatible Testo multifunction measuring instrument (please order separately) to determine air velocity, volume flow and air temperature.
Hot wire probe – features
Use the fixed cable to connect the hot wire probe to the measuring instrument.
The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. To ensure accurate measurement results, air density compensation is carried out via the integrated absolute pressure measurement.
The clearly structured measurement menu for volume flow makes the measuring instrument intuitive to operate. 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.
Integrated sensor protection: when you are not using the hot wire probe, the rotatable protective cap protects the air velocity sensor from dirt and mechanical stress.
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 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 air velocity and air temperature in ventilation ducts with reliability. Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the compatible measuring instrument (please order separately), configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away.
