Atago 3415 Digital Portable Wine Refractometer, WM-7 PALETTE Series with 7 Scales including Brix T.A. 1990 T.A. 1971 Oe (GER) Oe (Oechsle) KMW (or babo) Baume


Timeless Quality and Performance IoT Supported With Near Field Communication Technology

The WM-7 with 7 scales is a pocket Digital Wine Refractometer designed to operate of under the strictest environmental conditions, especially areas of high humidity of production and to measure concentration of grape must, easily, speedily, and accurately. Measurement of grape must concentration can be taken by winegrowers, wine cooperatives,wineries, buyers for grape must and so on. The measurement accuracy is upgraded to Brix ± 0.1%. Equipped with a new technology "External-Light-Interference" (E. L.I.)* that enable you to take accurate measurements with ease and confidence near at a window or outside.
*Patent Pending

In addition to the Bluetooth enabled refractometers, ATAGO ® released refractometers with near-field communication (NFC) technology for the ease of storing and sharing data with phones, tablets, laptops, and other NFC-equipped devices. Simply by tapping NFC-equipped devices, up to 100 measurement data with the date and time are transferred in a matter of seconds. The NFC solution is simpler and prevents typical human errors in data collection and data generation.

With ever evolving movement of profound change in how human interact with machine automation, this upgrade seizes one’s time to write down measurements with a pen or paper.

The Palette series - digital refractometers, are compact battery operated instruments that can display the measured values of samples quickly with one touch of the START switch.
