I think what you have to do is filter the rows according to measuretype
*before* you join them.  Something like

select * from
  (select depth, value as measuretype1_value from testtable
   where measuretype = 1040) ss1
  full join
  (select depth, value as measuretype2_value from testtable
   where measuretype = 4001) ss2
  using (depth);
