Test Equipment

This Specific Grape wine refractometer is used to measure the sugar content of the grape juice (see the Brix scale on the left) in the brewing process. Then, according to the sugar content of the grape juice, we can understand the alcohol concentration of the grape wine after brewing. It can measure both the sugar content of the grape juice and the alcohol concentration of the grape wine. It can not be used to test the alcohol concentration of the finished grape wine. It is equipped with Automatic Temperature Compensation (ATC), so that the fractometer is automatically adjusted to correct temperature discrepancies of environment temperature. Dual-scale design to measure the sugar content of the grape juice (0~40%) and the alcohol concentration of grape wine (0~25%). Easy to use, sturdy design, compact in size and light in weight, convenient to keep up and carry arround. We provide Manual in English, Russian. With Built-in ATC (Automatic Temperature Compensation) from 10~30 degree Celsius. Soft Rubber eyepiece for comfortable viewing Equipped with scale measurement which provides direct reading Accurate testing results guaranteed Durable and bulit to last long Adjustable manual focusing Use ambient light only which means battery or power source is not required

The brix and water content, and the baume are always importance to prove the honey's quality. Our honey refractometers are best tool to the farmer to test their honey. This optical refractometer (honey meter) has scales in the range of 12 - 27 % for measurement of honey moisture. The reading resolution is 1 %. It is suitable not only to beekeepers but also for all who needs check bee honey quality (e.g. in food industry).The other two scales offer possibility of reading the sugar content. It is widely used in the manufacture or production of sugar, food, fruit, beverages etc Easy to use, sturdy design, compact in size and light in weight, convenient to keep up and carry arround. We provide Manual in English, French, German, Spanish, Italian, Japanese, Russian. One Cloth bag for the convenient of customer is provided. With Built-in ATC (Automatic Temperature Compensation) from 10~30 degree Celsius. Cushioned with soft & comfortable non-slip rubber Soft Rubber eyepiece for comfortable viewing Equipped with scale measurement which provides direct reading Accurate testing results guaranteed Durable and bulit to last long Adjustable manual focusing Use ambient light only which means battery or power source is not required
