Technical Characteristics:
9.1
Hydrins II Probe
Measurement range
Two-way, from 0.02 m/s to 5 m/s, limited only by the stability and stiffness of the probe.
Fluid with conductivity of at least 20 µS/cm.
Precision
Point speed measurement: at mean or smoothed speed: ±2% if V
≥
10cm/s and ±2mm/s with respect to the
reading if V < 10cm/s.
Mean speed and volume: refer to the ISO 7145-1982 standard.
