The MASTER series has been improved with a clearer, brighter field of view and made even easier to carry. 
These improvements result in measurements which are especially clear when taking measurements in dim lighting, or measuring darkly-colored samples. Even when measuring milky-colored, opaque, or oily samples, the boundary line remains crisp and clear. 

The MASTER-53M and MASTER-53PM are the successor model of the conventional model, N-50E.
