Counter Tube Type FSZ

Counter Tube Type FSZ is a diving probe conceived for measurement of BETA- and GAMMA-RAYs.

In comparison to Counter Tube Type B this probe is larger and it allows – in addition to ordinary dry- and surface-measurements – the opportunity of highly precise measurement deep inside objects and large liquid volumes.

For this purpose the probe is equipped with a waterproof lace – 3 ft. of length (about 1 metre) which permits underwater measurement for professional demand.

Counter Tube Type FSZ is the most efficient model among our diving probes, appropriate to victual controls. Especially for mobile usage diving probes are much easier to handle as end-window Counter Tubes, for diving probes can be deposited on the object which you want to measure. This is normally not possible with end-window Counter Tubes.

Technical Data:

The tube is similar to Counter Tube Type B - just it is a double-tube.
