Current Meters

Aquadopp

Nortek Aquadopp

The Aquadopp is probably the most versatile single-point current meter on the market. It is cost-effective, robust and has a wide range of applications. The system electronics integrates accurate Doppler velocity measurements with standard sensors such as temperature, pressure, tilt, and compass. It is low maintenance, has no moving parts, requires no recalibration, and has no zero-point drift over time. The instrument can be used in real-time applications but also comes standard with an internal recorder, batteries and a highly sophisticated power management that makes it the system of choice for self-contained deployments.

Aquadopp 3000

Nortek Aquadopp 3000m

The 3000 m Aquadopp is designed for deployments down to 3000 m and it has all the capabilities of the standard Aquadopp. It is a modern, yet well-proven instrument and it is undoubtedly the most versatile single-point current meter on the market. 

Aquadopp 6000

Nortek Aquadopp 6000m

The 6000 m Aquadopp is “the big brother” in the line of Aquadopp models. The all-titanium mechanical housing is built to last at great ocean depths.
