The 6150AD-k probe uses a closed proportional counter that does not need to be purged with gas. Like the 6150AD-17 probe, it is sensitive to alpha, beta and gamma radiation but makes it much easier to scan larger surfaces due to its much larger sensitive area.
It also offers an electronic switch to the “Alpha” operating mode, in which only alpha radiation is detected and can be detected very sensitively because of the much lower zero effect in this operating mode. A removable discriminator plate (stainless steel, 1 mm) allows for distinction between beta and gamma radiation. The handle has a lockable joint and can be extended, e.g. for conducting measurements on the ground while standing.
