MiniWater6 Probes

Description

The MiniWater 6 probes are designed with a snaphead vane anemometer and a probe handle. The probe handle contains all the electronic components and comes with 2m cable with flying leads. All plastic snapheads are designed to be replaceable with an Aluminium vane for use in river and water courses to measure the flow rates. The MiniWater vane anemometers are available in two different sizes: Micro and Mini, with two different flow ranges available for each: 0-5ms; and 0-10m/s.
