CURRENT METER Rod Held Current Meter RHCM Portable device for point-by-point measuring for accessing the current speeds in running waters. The RHCM consists of a hydro-metric vane at the lower end of a telescopic rod and a splash-proof hand terminal.  The measuring head can be angled up to ±90°. The measuring values are displayed on a hand terminal, and the stored values are transferred to a PC by means of the software OceanLab 3.
