Multiple Water Sampler based on the LIMNOS-principle
This water sampler is intended for stationary deployment in depths up to 30 meters. Up to 10 samples will be taken at pre-programmed times within a total deployment time of up to one year. Both seawater and freshwater use cases are supported. Typical applications include long-term water quality monitoring in lakes or at seawater fish farms.
Just like the LIMNOS, the MULTI-LIMNOS Water Sampler meets two essential demands of researchers:
– avoiding sample contamination from surface water and
– avoiding errors in the analysis due to mishandling of the sample during transport and decanting
The system is equipped with 10 Duran glass bottles of 1 litre capacity each, which can also be used as transportation and storage containers.
After the bottles are filled with water, they are automatically closed by integrated check valves. The MULTI-LIMNOS is equipped with a microprocessor-controlled Motor Unit, the operation schedule of which is programmed via PC by using our OceanLab 3 software. Power is supplied by 3 long-lasting lithium batteries placed inside an external battery housing.
The MULTI-LIMNOS comes with a ball that floats on the water’s surface for keeping track of its position. State-of-the-art electronics, optimised in power consumption, are designed for ambient temperatures from -40°C up to +85°C.
It supports both bottom anchoring (basic configuration) for deployment from boats as well as conventional suspension via the optional stainless steel cage e.g. for operation from a boat or platform.
