Water Sampler for limnological and hydro- biological investigation. The closing mechanism has proved itself to be most satisfactory over many years; the water sampler is of simple and practical design and guarantees reliable results.
A thermometer ranging from -2 to + 30°C indicates the temperature of the sample; it can easily be read through the plastic tube of the sampler. The sample can be drawn off through the discharge cock in the lower lid for the various analysis.
