Envco – Environmental Equipment

SonTek’s graphical software suite provides quick and easy understanding of your results both in the field and office. With applications that span underway current surveys, nearshore deployments, benthic studies, or wave monitoring, the Mini-ADP is as robust and resourceful as you need it to be without sacrificing performance.

• Compact and light-weight
• Bottom-tracking for underway current surveys
• Directional waves
• Multi-sensor integration

The Mini-ADP features a unique frequency-based pressure interface for high precision sampling, a small (10 cm) diameter transducer head, and a non-corrosive package that is easy to mount and transport. So when you are looking for the best performance for your budget, the Mini-ADP is the obvious choice.
