How to Calibrate the Measurement Accuracy of Imported Portable Handheld Sugar Meter
The imported portable hand-held sugar meter needs to calibrate the zero point before measurement. Take a few drops of distilled water, put it on the detection prism, and turn the zero adjustment screw to adjust the dividing line to the 0% position of the scale. Then wipe off the detection prism for detection. Some models of instruments need to configure standard solution instead of distilled water when calibrating.
Another method is (only suitable for the determination of sugar content): use the temperature correction table to add (or subtract) the temperature correction value to the value read at the ambient temperature to obtain an accurate value.
Things to pay attention to when purchasing imported portable hand-held sugar meter:
1. When a user buys a product, he must first recognize his own needs before making an appropriate decision. The price of similar products varies from high to low, just like cars, there are 50,000 yuan and 500,000 yuan. Cars, but users’ needs and purchasing power are different. In order to meet different needs, high, medium and low-end cars are produced. From the perspective of buyers, choosing a product according to their own needs and purchasing power can also allow them to buy The same is true for hand-held sugar meters. Just like cars, hand-held sugar meters also have a variety of models to meet the needs of different customers, such as hand-held refraction sugar meters, or hand-held refraction salinity meters. The pursuit is Simple, practical and low in price, more people who need to measure the sugar content of the solution (or called the measurement of solid content) can obtain this product, and it can also be used quickly. At present, many domestic manufacturers produce hand-held sugar content meters. , basically all produce hand-held refraction sugar meters. Different regions and different manufacturers produce different prices, but generally the price is several hundred yuan, and they are all hand-held sugar meters designed on the principle of light refraction. All hand-held sugar meters are not waterproof. During use, be careful not to let water wash the hand-held sugar meter directly, and store it in a dry environment.
2. When purchasing, choose a merchant with a warranty. Usually, if there is water in it, the merchant will not guarantee it, because the maintenance cost is high, and most merchants suggest that customers buy a new one. If the merchant provides water for the handheld sugar meter Warranty is also very rare, so a certain fee may be charged, so that better protection can be obtained. Usually, the service life of a hand-held sugar meter is more than 2 years, but the premise is that it must be well maintained.
