Hand-held saccharimeter is also called refractometer. Its measuring principle is to determine the density or specific gravity through the refraction of light by the solution. Hand-held saccharimeters are mainly divided into ordinary manual reading saccharimeters and digital display saccharimeters. Different saccharimeters and reading methods different.
Ordinary hand-held brix meter adopts scale reading, the specific reading method is:
1. Drop 3-4 drops of the juice to be tested onto the prism without bubbles;
2. When looking at the sun or light, you can see the blue-white dividing line. At this time, the number corresponding to the blue-white dividing line is the degree of the liquid you are measuring.
It should be noted that this type of hand-held brix meter needs to be calibrated before measurement. The calibration method is:
1. Open the cover, drop 3-4 drops of calibration liquid onto the prism, and cover the cover so that no bubbles can be generated;
2. Look in from the eyepiece to see if the blue and white dividing line is on the "0" scale. If not, please use the built-in screwdriver to turn left and right at the correct point and adjust it to the "0" scale line;
3. Wipe off the moisture with wet wipes or the rag that comes with the instrument.
The reading method of the digital display brix meter is relatively simple and convenient. After the measurement is completed, the measurement data will be directly displayed on the display of the instrument, and the value can be directly read. This type of brix meter needs to be zeroed before testing. The specific method is to use distilled water to zero-adjust the brix meter.
After the test is completed, all need to be cleaned. Rinse the Brix meter and juicer with clean water, and wipe the water droplets with a paper towel.
Hand-held brix meter has the characteristics of simple operation, convenient carrying, convenient use, less measuring liquid, accuracy and speed, etc. It is a commonly used instrument in sugar industry inspection, fruit inspection, food and beverage, mariculture, scientific research and mechanical processing industries.
