Digital Gemstone Refractometers
-
Product Highlights- 【3 in 1】one screen and three displays. the instrument can measure temperature, brix and refractive index.
- 【waterproof】the instrument can flush the sample tank with water, but it cannot be immersed in water for a long time
- 【language switching】press and hold the zero key while turning on the computer to switch between chinese and english interfaces 【widely used】measure the sugar content of fruit, juice and beverage； 【wide measuring range】0-55%brix； 【resolution】0.1%brix
- 【temperature compensation】10-40 ℃ automatic temperature compensation, 10 ℃ for temperature compensation below 10 ℃, and 40 ℃ for temperature compensation above 40 ℃
- 【zero-setting】measure whether the clean water or pure water is 0.0% before using, and if it is not 0.0%，it will be zeroed first. 【easy to use】keep about 1 mm between dripped water or pure water and the top of the measuring slot, and the capacity is about0.3 ml.press the"meas" key to display the value.
