IWS Integrating Water Sampler Version II

The IWS sampler has been developed to take integrated samples from a watercolumn in accordance to meet the proposed requirements of the EU-WFD.

The sampler is equipped with a small motor unit on top which is controlled via the built-in pressure sensor and a small electronic control unit. This will guarantee a complete sampling of the whole water column up to the desired depth. Power supply is given by recharchable Ni-Mh accumulators.
New in Version II :

Power Unit is mounted outside in a separate housing
Quickstart-button– will activate the sampler when using the same depth programming as before
Protocol - integrated in OceanLab3 Software

The IWS II is very simple to use:

The desired depths ( start and a final depth free selectable) are programmed and stored in the sampler via handterminal or pc with OceanLab 3 Software. The recommended speed for lowering is shown in the display. Then the sampler is lowered into the water. The electronics will regulate if lowering is not constant - moving of the boat or rough sea etc. After reaching the final depth the sampler can pulled up with a total content of 2.5 or 5 litres. Due to the free selectable depth it is possible to get samples even from a segment of the water column.
