Unique Group was one of the first companies to recognise and promote these new generation ADCPs. These units are now the backbone of our ADCP fleet having taken over the reign from TRDI Workhorses.

The Signature500 ADCP is designed for flexibility. It measures current profiles at up to 8 Hz sampling frequency. It can also measure direct vertical velocity profiles, wave height and direction, and ice thickness and drift.

The Signature1000 ADCP is the optimal tool for turbulence measurements. With a maximum sampling frequency of 16 Hz, it gives the scientific community an unprecedented opportunity to study a part of the turbulence spectrum that has never been accessible before. Vertical resolution current profiles of 2 cm over a range of up to 8 m further increase the Signature1000’s versatility, as does its ability to measure wave height and direction.

The center beam of both systems also functions as a biological echosounder, enabling high-resolution measurements of biomass in the water column.

Specifications for both frequencies are available.
