I don't know if the one by Zircon is still made.    It was called the 
"video level", since it has a small LCD display.  What makes it usable 
by the blind is that it  emits a steady audio tone  when either level or 
plumb.  It's only 10 inches long, but can be  attached to a longer 
straight edge if needed.

Got mine in 2005 from one of the blind product suppliers.  Around $35 at 
the time.   Not sure it is still made, but Zircon makes a lot of stud 
finders and stuff like that, and it may still be around.
