Turbulence measurement in accordance with EN 13779
Determination of air velocity and draught risk
Integrated temperature and ambient pressure measurement
Intelligent calibration concept

Draught is the most common cause of complaints about indoor climate. Use the comfort probe to determine turbulence. Turbulence corresponds to the extent of fluctuations in air velocity over time. It is needed to calculate the draught risk. The probe enables you to determine air velocity and draught risk in accordance with EN 13779. The probe can also measure temperature and ambient pressure at the same time.

Intelligent calibration concept

The probe offers maximum digital measurement reliability. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. The probe can be sent in for calibration on its own (without the measuring instrument). Calculating the determined calibration data in the probe generates a zero-error display.
