Manufacturer: Vee Gee Scientific Inc. Brand: Bellwether

Hydrometer, Specific Gravity 0.900 to 1.000. Calibrated at 60°F Specific Gravity, also known as relative density, is the ratio of the mass of a solid or liquidto the mass of an equal volume of distilled water. The standard temperature of calibrationin the U .S. is 60°F/ 60°F. All Bellwether Specific Gravity Hydrometers listed are calibratedat 60°F/ 60°F

This model RHW-80ATC works for alcohol testing (to test the alcohol concentration in the alcohol solution, not the grape wines or the other fruit wines). Its unit is W/W (Weight/Weight), the refractometers working temperature is suggested at 20°C (about 18°C to 25°C). Measure the alcohol content accurately in seconds! All you need to do is manufacture a distillate of the liquids to be measured, and then place the distilled sample on the prism. Many of the refractometers on the market are made of plastic. However, people who work with alcoholic beverages or industrial fluids on a regular basis believe that metal refractometers provide more accurate measurements and that they simply stand up better over time and provides you with fast, accurate results - the very same characteristics that you get with all our Refractometers. Features: Heavy-duty and lightweight with its aluminum construction High quality and accurate testing results are guaranteed Equipped with Built-in ATC compensation Range (Automati...
