Technical data Feature

Values

Flow measuring range 0 to +5 m/s Temperature measuring range

0 to 50 °C (probe head)

Operating range, handle

0 to 40 °C

Accuracy (at nominal temperature 22 °C) ± 1 digit

±0.5 °C ±(0.03 m/s + 4% of meas. val.) At low air velocities, slightly increased temperature display!

Absolute pressure sensor

measuring range: +700...+1100 hPa Accuracy: ±3 hPa

Adjustment conditions Wind tunnel, adjusted in free jet Ø 350 mm, reference pressure 1013 hPa, flow against testo logo The digital probe allows measurement values to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. For calibration, the probe alone (without the hand instrument) can be sent away. Entering the determined adjustment data via the EasyClimate software generates a zero-error display. === Ende der Liste für Textmarke Inhalt ===
