How to calibrate the measurement accuracy of a handheld sugar meter?
The imported portable handheld sugar meter needs to calibrate the zero point before measurement. Take a few drops of distilled water and place them on the detection prism. Turn the zero adjustment screw to adjust the dividing line to the 0% mark position. Then clean the inspection prism and perform the inspection. Some models of instruments require the preparation of standard solution to replace distilled water during calibration.
Another method is (only suitable for measuring sugar content): use a temperature correction table to add (or subtract) the temperature correction value read at ambient temperature to obtain accurate values.
What to pay attention to when purchasing an imported portable handheld sugar meter:
1. When purchasing a product, users first need to recognize their own needs in order to make appropriate decisions. Similar products have different prices, just like cars, which cost 50000 yuan and 500000 yuan. However, the user's needs and purchasing power are different. In order to meet different needs, they produce high, medium, and low-end cars. From the perspective of buyers, selecting a product based on their own needs and purchasing power can also help them buy a satisfactory product; The same goes for handheld sugar meters. Just like cars, there are various models of handheld sugar meters that meet the needs of different customers. For example, handheld refracted sugar meters or handheld refracted salinity meters pursue simplicity, practicality, and low price. They can allow more people who need to measure the sugar content (or solid content) of a solution to obtain this product, and can also be quickly used. Currently, many manufacturers of handheld sugar meters in China basically produce handheld refracted sugar meters. The prices vary depending on the region and the manufacturer, but they are generally several hundred yuan in price, and they are all designed based on the principle of light refraction. And all handheld sugar meters in China are not waterproof, so be careful not to let water directly rinse the handheld sugar meters during use, To be stored in a dry environment
2. When purchasing, choose a seller with warranty. Usually, if there is water inside, the seller does not provide warranty because the repair cost is high. Most merchants recommend customers to purchase a new one. If the seller provides warranty for the handheld sugar meter that has water, it is also very rare, so they may charge a certain fee to obtain better protection. Generally, the service life of the handheld sugar meter is more than 2 years, but the premise is that it must be well maintained.
