| SeaPac
2000
Current Gauge The SeaPac 2000 is an electro-magnetic current meter specifically designed for the difficult coastal ocean environment. |
| For the Research Scientist, the Consultant, and Industry, the SeaPac 2000 offers unique advantages: |
 |
| Versatile | -Stores raw x and y currents or
true vector averaged east and north currents
-Offers optional tilt compensation and pressure sensor -Has extra input channels (analog and digital) for interfacing a wide variety of other sensor types |
| Accurate | The sensor suite is a recognized
industry standard:
-Marsh-McBirney EM current sensor -KVH digital fluxgate compass -YSI precision thermistor |
| Easy to Use | -Set-up & download directly
through the endcap
-Output in ASCII Hex or engineering units -Removable memory pack allows quick re- deployment |
| Data Analysis | Optional CurrentPro Software
provides fast analysis and presentation of your data using the MATLAB environment.
