Which model of analytical balance is durable?
Thread Content
The AL-204 type analytical balance we are using is not very useful; which model of balance would be better?
It mainly depends on the precision you need for weighing – one in ten thousand or one in a hundred thousand, depending on your requirements. We use Mettler-Toledo equipment, which is quite durable.
Among foreign products, besides those from Mettler-Toledo, Sedolis is also quite commonly used. Domestically, Xiangyi models have been used (one is still in use currently; no further purchases were made later on). It seems that there are quite a few manufacturers of domestic electronic balances these days. Those who have used them might want to share their experiences; I personally prefer to support domestic products.
Both the domestic and imported Sedolis models are quite durable; we’ve been using ours for 6 years without any problems (domestic model)
After selecting a balance, the most important thing is to maintain it and calibrate it regularly, as this will extend its lifespan. We used imported balances in the past, but we didn’t take good care of them; after just over a year, they were in terrible condition
We use all Japanese products; the power supply voltage is 100V, and the accuracy is quite good
There are now many types of domestic electronic balances available, but among them, those from Shanghai Jingke are considered to be of relatively high quality. Among foreign brands, there is the AUY220 from Shimadzu as well as those from Mettler Toledo. The lifespan of such equipment depends on whether the person using it takes good care of it; just as with people, if you treat equipment well, it will in turn serve you well
Reply 6# *lihuagong: How can a power supply of 100V be provided?
Reply to 8# Egu Ting: Most of the analysis equipment in our laboratory is of Japanese origin, and the power supply used for those Japanese devices is 100V. That’s why our power plugs are available in both 100V and 220V versions.
Buy a small transformer from any electrical supply store; it should have an input of 220VAC, as long as it comes with taps for 100 or 110VAC. It is estimated that the power consumption of the electronic balance will not exceed 100W, so a small fixed-output transformer will suffice.
Many foreign scales are troublesome to use; domestic ones are better as they are more familiar. We must firmly resist Japanese products and support domestic ones
