MASTER series has recived several awards!!

  • 2006 “ Good Design Award “
  • 2007 “ The Invention Prize “
  • 2007 “ Japan Patent Office Commissioner Encouragement Prize “
  • 2009 “ Minister of Education Award “
Protection class of the MASTER-α, H series are IP65. You can rinse off the sample by running water on the prism. The design allows the user to easily wipe off the sample.Sample size 2-3drops.
The Automatic Temperature Compensation function of the MASTER-α, T, H series enables you to take measurement readings regardless of the ambient temperature.Automatic Sample Distribution (ASD)
New prism housing design allows for sample to cover the prism without having to lift the day-light plate! This design will allow forfast & easy measurements.
Convenient Storage case.  

The MASTER series has been improved with a clearer, brighter field of view and made even easier to carry.

Compact Redesign of the MASTER Series (from October 2014)
The MASTER series has been improved with a clearer, brighter field of view and made even easier to carry.
These improvements in our newly compact redesigned models 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.
Note: The size of the scale has changed. It may take some time to re-adjust to the new field of view when reading measurements.
