12-Inch Passive DRYSTIK

Passive DRYSTIK wand to detect radon entry points

 
 

The 12-Inch Passive DRYSTIK consists of open tubing with a wand-like handle that can be aimed at possible radon sources. The Passive DRYSTIK will preserve a container of desiccant for two months of continuous use, a significant improvement over its standard useful life span of 10 days.

Principle of Operation

The Passive DRYSTIK operates on a principle involving two tubes, one inside the other. The inner tube is made of NAFION, a Teflon based material that permits the movement of water molecules, while blocking air and radon. The air sample flows along the inner tube on its way to a drying unit, while the space around the inner tube is purged with dry air coming from the outlet of the RAD7.
