Overview:
Widely used in sugar, food , beverage and other industrial sectors and agricultural production and scientific research . Suitable for measuring the concentration of soy sauce, ketchup and other sauces ( seasonings ) products for jam, syrup , sugar and other sugary liquid measuring Brix more products for juice , soft drinks and carbonated beverage production line quality management, pre-delivery inspection , etc., for the sweetness of the fruit as a hierarchical classification from planting to the sales process .

Use the steps:
1. the refractive index of the prism light alignment direction , eyepiece diopter adjustment ring, until the marking is clear.
2. Adjust the reference:
Measured before the first use of the standard solution ( zero scale for pure water, the range is not zero starting point scale, was using the corresponding standard solution ), based on the same instruments and test liquid temperature. Opened the cover, then take 2 to 3 drops of liquid droplets on a standard refractive prism, and gently press the flat plate, see a blue and white dividing line through the eyepiece. Rotating bolt calibration eyepiece field of view of blue boundary coincides with the baseline (0%) (Note: This optical instrument factory calibration, and can be used directly).
3. the measurement:
Use a soft cloth to wipe the surface of the prism and cover, opened the cover, take 2 to 3 drops of test solution was dropped on the refractive prism, Close the lid gently press the flat, which do not have air bubbles, and then read eyepiece blue boundary relative scale, namely the content of the measured liquid (mostly percentage, 0-10% per thousand salinity meter for specific gravity).
4. after the measurement is completed, clean the prism surface and direct attachment on the cover with a damp cloth, after drying, keep it up.
