First introduce the electronic scale level:
1. Low-grade electronic scales: scales for selling vegetables, weighing glass surfaces, portable scales, etc. The price of such scales is 60~300 yuan. Mainly the quality of the weighing components, the product error (linear, repeatability), suitable for personal weighing is used.
2, mid-range electronic scales: weighing, counting electronic scales, in line with the national measurement standards of the [III] accuracy level. The product quality is general, suitable for general weighing occasions (trade, enterprise measurement). The price is about 600~1000 yuan.
3, high-accuracy electronic scale: In fact, as long as the electronic scale is the [III] accuracy level, the true high accuracy should be called the balance [III]. The display scale value of the electronic scale is high, and the actual verification scale value is also the [III] accuracy of the electronic scale, and the verification scale value E=10D. The user can see a small display scale value. This kind of electronic scale is suitable for scientific research, metering and use within the factory, and cannot be used for trade settlement. The price of this kind of electronic scale [also called balance] is about 1000~2000 yuan. Note: If you call Tianping, the metrological verification fee is about 300 yuan, and the electronic scale verification fee is about 20 yuan.
Let me talk about the electronic scale performance identification method:
1. Appearance inspection: The material of the electronic scale is good or bad, the design of the button is reasonable, and the display is easy to read.
2. Accuracy: The zero point must be stable, and it can be quickly returned to zero after the item is finished. Repeatedly said the unchanged item display value can not be exceeded, linear error check (1/3, 2/3, 3/3 weight of the maximum weighing), the smaller the above error, the better.
3, the function of the electronic scale is practical, this must be based on their own needs, more features, the price is high.
4, as long as it is a national standard measuring instrument, the manufacturer must have (measurement device production license 怔) products must have a certificate, warranty card, instructions for use, accessories.
5, from the electronic scale warranty provisions and related product documentation can basically see how the manufacturer's comprehensive reputation.
Now is the market economy, the cost-effectiveness of the product is too big, a little feeling, for reference only, please correct me if it is not appropriate.
