China Education Equipment Purchasing Network News: People call the balance that uses the electromagnetic force to balance the gravity of the object called the electronic balance. It is characterized by accurate and reliable weighing, fast and clear display, and has automatic detection system, simple automatic calibration device and overload protection device.
Electronic balance, used to weigh the mass of objects. Electronic balances generally use strain sensors, capacitive sensors, electromagnetic balance sensors, strain sensors, simple structure, low cost, but the accuracy is limited, currently can not achieve very high precision; capacitive sensors weigh fast, cost-effective , But can not achieve very high precision; electronic balance using electromagnetic balance sensor. It is characterized by accurate and reliable weighing, fast and clear display, and has automatic detection system, simple automatic calibration device and overload protection device.
Noted elements:
1. The quality of electronic balance price products and necessary additional functions. The balance includes accuracy, linearity, repeatability, and four-corner error. Electronic analytical balances do not have reliable quality assurance, and balances cannot guarantee the accuracy of later experimental results. The necessary additional functions of the precision balance can ensure the simplicity and smoothness of the experiment.
2. The price of the electronic balance is excellent, and the balance avoids excessive consumption. Electronic balances do not need to cost money for functions that are not needed. The product quality of electronic balance manufacturers is guaranteed. When the performance of the electronic balance is basically the same, the price of the electronic balance is more favorable to ensure the efficiency of the use of funds by units or individuals. Electronic balances are welcome to use the economic brands of classic manufacturers.
3. The average annual use fee of the electronic balance quotation. The electronic balance factory includes natural losses and maintenance costs. For example: the purchase price of one ten thousandth electronic balance product is 4,000 yuan, and the purchase price of 2 electronic balance products is 6,000 yuan. If the product life of one thousandth is 3 years, the service life of 2 electronic balance products is 9 years. 2 balance products are cheaper per year. The electronic balance mentioned above does not include the loss and maintenance costs caused by the interruption of the experiment due to the frequent return of repairs.
4. The compatibility of the electronic balance to the operator and the tolerance to the operating environment. The operation of users of electronic balances is different, 1 electronic balance products often have large errors, 2 electronic balance price products are operated by different personnel, and the balance results are basically the same. With the same precision, the products of 1,2 balances have different tolerance levels for electronic balance handling, electronic balance use, electronic balance maintenance, electronic balance vibration source, electronic balance temperature, and precision electronic balance humidity.
5. After-sales service and functional expansion of electronic balance products. The balance avoids quality problems as much as possible. If the balance has quality problems or needs function expansion, the balance classic manufacturer can provide timely and thoughtful service. The market for electronic balances is fiercely competitive, and only companies with survivability and basic profits can provide long-term and thoughtful service and technical support.
