Compact Water Sampling System for Oceanography and Limnology
The compact version of the Multi Water Sampler MWS SlimLine 6 is an instrument designed for the collection of water samples in successive water layers. Only one operation for 6 different samples! The sturdy stainless steel array is equipped with six racks to which Plastic Water Samplers with capacities of 1, 3.5 or 5 litres (depending on model selected) can be mounted.
Due to its compact dimensions and light weight it can easily be handled even on small vessels. The MWS SlimLine 6 is equipped with a motor-driven release device with an integrated Depth Meter (measuring range according to customers’ requirements). The water samplers are sequentially closed in the succession of their mounting to the array (i.e. No. 1, 2, 3, …). The state-of-the-art electronics, optimised in power consumption, are designed for ambient temperatures from – 40°C up to +85°C. The maximum operational water depth is 3000 metres. A special version for operational depths down to 6000 metres is available upon request. The MWS SlimLine 6 is generally delivered for combined Online/Offline use and is therefore the ideal all-purpose rosette system for use on research vessels with limited deck space.

The water samplers are actuated via push-button control by the mains operated Deck Command Unit. The commands for actuation of the water samplers are given via a single or multi-conductor cable between the Underwater Unit and the Deck Command Unit or PC. The Deck Command Unit is equipped with a serial port for data transfer to PC.
OFFLINE
In case that a conducting cable is not available on board, the required sampling depth can be pre-programmed via personal computer. The actuation of the water samplers is then carried out automatically according to the pre-selected depth intervals. All measuring data are stored inside the internal data memory (16MB) during the operation and can be read out by a PC when the system is back on board.
