With the development of modern sensor technology,electronic balance industry has developed rapidly,the market more and more types of electronic balance,for our ordinary consumers,how to buy electronic balance becomes more and more difficult.In fact,the main thing we have to see our needs,the average user does not need too much accuracy requirements,and as gold shops,laboratories and other places on the higher accuracy requirements,so this time should choose a high precision balance,Of the time to buy electronic balance to note the following six elements.
1.The quality of the product and the necessary additional functions.Including accuracy,linearity,repeatability,and square error.Electronic balance is the basic laboratory equipment,there is no reliable quality assurance,can not guarantee the accuracy of the results of the latter part of the experiment.The necessary additional functions to ensure the experiment simple and smooth.
2.Excellent cost-effective to avoid excessive consumption.It is not necessary to spend money on functions that do not need.In the electronic balance of quality assurance,performance is basically the same case,a more favorable price to ensure that the unit or individual funds use efficiency.Welcome to the classic manufacturers of economic brands.
3.Average annual usage fee.Including natural wear and maintenance costs.For example:A product purchase price of 3,000 yuan,B product purchase price of 6,000 yuan.If A product life of 2 years,B product life of 5 years.In fact,B is the average annual cost of the product is cheaper(1,500 yuan/year:1,200 yuan/year).The above does not include the A product due to frequent repair problems caused by the interruption of the loss and maintenance costs.
4.Compatibility of the operator and tolerance to the operating environment.Different personnel operating practices are not the same,A products tend to larger errors,B products different personnel operations,the results are basically the same.The same accuracy of A,B products,handling,use,maintenance,vibration source,temperature,humidity and other requirements are not the same degree of tolerance.
5.After-sales service and product development.As far as possible to avoid quality problems.If a quality problem or the need for functional expansion,the classic manufacturers can provide timely and thoughtful service.Market competition,viability and the basic profit of the enterprise can provide long-term and thoughtful service and technical support.
6.User-friendly design.To avoid the occasional operational errors caused by damage to the instrument.While ensuring that users use the process of light,comfortable,pleasing.
