Precision level
* For the smallest model (150 mm), a refl ector is 
   not provided. 
* This level do not have an air chamber.
・By sticking magnetic planes to columnar items, the angularity can be measured 
  with high accuracy.  
・ Since the magnetic plane sticks to an item to be measured, an indicated 
  value can be read even when removing your hand. This allows for safer measurement in high places. 
・A measured value can be read easily with the refl ector.
