SonTek 16-MHz MicroADV

Product discontinued. Please refer to other Velocity & Flow Meters.

The SonTek 16-MHz MicroADV (Acoustic Doppler Velocimeter) is the most significant breakthrough in 3-axis (3D) current meter technology since the original SonTek ADV. The original SonTek ADV has compared favorably with Laser systems costing ten times as much — the MicroADV fares even better. The higher acoustical frequency of 16 MHz makes the MicroADV the optimal instrument for laboratory work. Like all SonTek instruments, the MicroADV is extremely simple to set up and use. Most users are taking high-quality data within minutes of receiving the system.
