This is for a pre-owned Constant Electronic Hand Dynamometer.  #14192-709E.  Max 90Kg/198lb.  Requires 2 "AAA" batteries (not included).  Digital display.  Works Great!  There is some sticker residue on the back.  Comes from a smoke free home.  Once payment has been received I will ship out the same day or the next morning.  Thanks for looking.
