вопрос.
не могу сформулировать перевод названия прибора, чтобы он мне понравился:
the Wet & Dry Sampler and the Wet Only Sampler (две разновидности типа)

Вот контекст:

The influence of acid precipitations on the natural ecosystems in the long run is very well known by now. Studies have been conducted over the past years to evaluate and control the risks deriving from dry and wet depositions and their impact on forests, cultivations and shallow waters.

MTX has designed two kind of automatic samplers for this purpose: the Wet & Dry Sampler and the Wet Only Sampler.
