Wet&Dry + QAS22024 Passive Sampler (Mains Power Supply)

Wet&Dry + QAS22024 - passive sampler (mains power supply)

The Wet&Dry is a passive sampler used for the collection of the atmospheric dust and bathed depositions, generated from the rainy and snowy precipitations (wet) and from the dust depositions (dry) realized in accordance to the European legislation 2004/107/CE. The wet and dry deposition can be distinguished collected in two or more separate containers removable for subsequent analyses, thanks to the sensor that in case of rain, closes the collector of the dry depositions and opens the one of the wet depositions.

The sampler is equipped with heating system both for the rain sensor and rain gauge that detects also snowy events, ice or hail, (only with optional primary power supply). Revised with a robust mechanical, it now offers the status of contacts for analysis on time bases. Such shrewdness allows the sampler Nesa Wet&Dry to be particularly adapted in all the environmental conditions (-30 ÷ +70 °C).

The use of materials like the anodized aluminium and stainless steel, guarantees an excellent resistance against corrosion due to the atmospheric agents, assuring a high durability.

It’s also available in the solar panel version for one totally independent power, or primary 220Vac.
