0635 1571 – Testo Hot Wire Probe (Temperature and Humidity Sensor) w/Bluetooth * For Testo 400 & Testo 440
May require additional shipping time, usually ships in 2-3 weeks. Contact Us for more information on availability.
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.
- 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
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.
