Refractometer Brix 0-90% Brix Meter Refractometer for Measuring Sugar Content in Fruit, Honey, Maple Syrup and Other Sugary Drink, with Automatic Temperature Compensation Function

Refractometer Brix 0-90% Feature: With Built-in ATC compensation Range (Automatic Temperature Compensation) from 10°C to 30°C For field use, without having to re-calibrate after changes in ambient working temperature. Soft rubber eye piece for comfortable viewing Equipped with scale measurement which provides direct reading Accurate testing results guaranteed Extremely easy-to-use and calibrate Durable and built to last long Adjustable manual focusing Uses ambient light only which means battery or power source is not required. Cushioned with soft & comfortable non-slip rubber Only can be used before fermented, can not test the beer which already be done. Specifications: Brix scale: 0~90%Brix; Reference Temperature: 20°C ATC(Automatic Temperature Compensation) Compensation Range: 10°C~30°C (50°F~86°F) Manual calibration with mini-screw driver provided Operation Steps: 1.Open Daylight Plate, and place 2~3 drops of distilled water on the main prism. 2.Close the daylight plate and gently press it, so the water spreads across the entire surface of the prism without air bubbles or dry spots. 3.Wait 30 seconds to allow the sample to come to the ambient temperature. 4.Hold daylight plate in the direction of a light source and look into the eyepiece, you'll see a circular field with graduations down the center. 5.You may have to focus the eyepiece to clearly see the graduations. The upper portion of the field should be blue, while the lower portion should be white. 6.Take the reading where the boundary line of blue and white cross the graduated scale. 7.Clean the instrument by using a soft and damp cloth after measurement, keep it up after dried. How to calibration Use the distilled water to calibrate to "0",since the distilled water's BRIX Content is 0%. Ensures accurate measurement and focus adju

• Large Scale Range; brix 0-90% large scale range makes it be suitable in wider field. This refractometer is almost equivalent to a regular brix plus a honey refractometer, but you just need to spend about half money.
• Easy to use; Just take a few drops of your liquids on the prism and hold the refractometer to the light, then look through the eyepiece, you can get the reading. No need lookup table and no waste!
• Safe and durable; This refractometer is constructed with non-staining, non-corrosive and non-reactive Aluminum plating material which make sure hygiene and safety for all users.
• Portable compact package; The refractometer comes with dropper, screwdriver, user manual and cleaning cloth, all included in a hard compact case, the item dimensions is 8"x3"x2", the item weight is only 8.8 ounces. makes it very portable and easy to carry.
• Widely used; 1 Used for sugar content control in food & beverage producing. 2 Used for monitoring ripeness of growing plants, fruits & vegetables. 3 Used for science research, clinical laboratories.
