How to calibrate the measurement accuracy of the imported portable hand-held sugar content meter?
Imported portable hand-held sugar content 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 clean the inspection prism and perform inspection. Some models of instruments need to be equipped with 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.
Problems to pay attention to when purchasing imported portable hand-held sugar content meter:
1. When a user buys a commodity, he must first recognize his own needs before making an appropriate decision. Similar products have high and low prices. Just like a car, there are 50,000 yuan and 500,000 yuan. The same is true. Cars, but the needs and purchasing power of users are different. In order to meet different needs, high, medium and low-end cars are produced. From the perspective of buyers, purchasing a product according to their own needs and purchasing power can also allow themselves to buy To a satisfactory product; the same is true for a hand-held glucometer, just like a car, there are many models of hand-held glucometer to meet the needs of different customers, such as a hand-held refractometer, or a hand-held refractometer. Salinity and other products, the pursuit is Simple, practical and inexpensive, it can allow more people who need to measure the sugar content of the solution (or measure the solid content) to obtain this product, and it can also be used quickly. At present, there are many domestic manufacturers of hand-held sugar meters , Basically they are hand-held refractometers, which are produced by different manufacturers in different regions, and the prices are different, but generally the price is several hundred yuan, and they are all hand-held sugar meters designed by the principle of light refraction, and domestic All hand-held glucometers are not waterproof, please be careful not to let water directly rinse the hand-held glucometer during use, and store it in a dry environment
2. Choose a merchant with warranty when purchasing. Usually, if water enters the merchant, the merchant will not guarantee it. Because the maintenance cost is high, most merchants recommend that customers buy a new one. If the merchant provides a hand-held saccharide meter for water Warranty is also very rare, so a certain fee may also be charged, which can also obtain better protection. Usually, the service life of the hand-held glucometer is more than 2 years, but the premise is that it must be well maintained.
