Determining the degree of turbulence with turbulence probe and testo 440
The digital turbulence probe, designed for measuring air velocity and temperature, helps determine the degree of turbulence and draught risk in compliance with EN ISO 7730 / ASHRAE 55.
  • Intuitive operation – Clearly structured measurement menu for determining turbulence and draught risk.
  • High precision – Compact probe for measuring air velocity and air temperature, even at low velocities.
  • Convenient use – Optional measuring tripod for standard-compliant probe positioning.
  • Intelligent calibration – Ensure exceptionally accurate results with easy calibration adjustments.
The Testo Turbulence Probe is an essential tool for accurately determining air velocity, air temperature, and the associated degree of turbulence and draught risk in workplaces. By connecting the probe to a compatible testo multifunction measuring instrument (sold separately), users can measure these parameters and calculate the draught risk according to EN ISO 7730 / ASHRAE 55.

Designed with precision in mind, the probe is compact and offers high accuracy, even at low air velocities. It features an intuitive, clearly structured measurement menu for ease of use. The probe also includes air density compensation via integrated absolute pressure measurement, ensuring reliable results under various conditions.

For standard-compliant positioning at varying heights, the optional measuring tripod (sold separately) is recommended. This ensures the correct placement of the turbulence probe to capture the necessary data for a comprehensive assessment of comfort levels in the workplace.

This probe is ideal for assessing the degree of turbulence and draught risk in indoor environments, helping to identify discomfort factors that can affect the overall indoor climate. The digital turbulence probe is a vital tool for improving workplace comfort by addressing draught-related issues efficiently.
