Reason to choose MASTER series


Water resistant（α & H 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.

Visibility

Visibility

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.

Contamination free

Contamination free

Uses a smooth grip with no irregularities. The carbon-like design contributes to both cleanliness and playfulness.

ATC Temperature compensation（α・H・T series）

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.

Durability

Cleared all tests of waterproof, dustproof and droptest. Water was sprayed from four directions, dropped on oak sleepers from a height of 1 m, and loaded in the cargo compartment of an airplane, and passed all durability tests.

Design

Waterproof, Visibility, Contamination-free, ATC, Durability, ASD. The harmonious design has won numerous awards such as the Good Design Award and the Invention Award.

After-sales support

We are building a close network with our service centers in all over the world.In addition to repairs, we also provide support such as tips on measurement methods.

ATAGO's Social trust

A history of over 70 years has steadily built up social trust. Its roots are deep and wide, and it has been exported to more than 154 countries.
