Hi All,

My experience with the BD tritium monitors is that they do not have
automatic range changing. (i.e., 1960's electronics).  If the monitor is
set at the most sensitive range, and the tritium concentration goes up
by a factor of 10 or more, and you are not there to click the knob to
the next higher range, the data are lost! 

Maybe BD has finally fixed this problem. Maybe not.

cheers,
Wes
