Reason to choose MASTER series
Water resistant（α & H series）
"Washable". A special design concept for analog type measuring instruments. It is a new mechanism that can be washed even under running water after measurement.
The readability of measured values is the "lifeline" for hand-held refractometer.Not only the brightness of the entire field of view, but also the clarity of the boundaries represents the basis of the optical technology that ATAGO has reached.
Uses a smooth grip with no irregularities. The carbon-like design contributes to both cleanliness and playfulness.
ATC Temperature compensation（α・H・T series）
The measured value are automatically corrected according to the environment. We have thoroughly improved the structure and arrived at a mechanism, patented that is not found anywhere else.
