Choose An Electronic Balance
The electronic balance is the latest type of balance developed in the balance. It is one of the weighing instruments commonly used in industrial manufacturing and chemical laboratories. It has the advantages of fast weighing and convenient use.
However, there are too many brand balances. How to choose 0.01g laboratory electronic balance is also a headache. Today I will teach you some simple ways to choose the balance that suits you.
1. Positioning type
First of all, you have to determine the accuracy of the waterproof electronic balance you need. There are 0.01g percentiles and 0.01g thousandths, and many more. The most commonly used are percentiles, thousandths, and tenth percentiles. Some laboratories or special industries may need to use percentile scales. Once determined, you can narrow down the selection.
2. Process and accessories
When we get the same product, we are all looking at how beautiful it is. You can see if the balanced connection is flat and if there is a gap. Whether the key design is reasonable and whether the display is easy to read. Is the weighing pan made of stainless steel? Is the balance frame made of aluminum alloy? Is it equipped with a windshield? The windshield can play a certain role in an unstable environment. As long as it is a national standard measuring instrument, the manufacturer must have (the product of the measurement instrument production permit the production must have a certificate, warranty card, instruction manual, and accessories.
3. Response speed and accuracy
The zero point must be stable and be able to return to zero quickly after weighing the item. I don't think anyone would want to buy a balance that reads like a snail. Repeatedly, weighing of the same item does not show the difference. Linear error check (1/3, 2/3, 3/3 of the maximum weight), the smaller the above error, the better.
4. Repeatability and stability
Repeatability actually refers to the consistency between the results obtained by performing multiple consecutive measurements on the same measurement object under the same measurement conditions, which is called the repeatability of the measurement results.
You can weigh out a small object first, remember the weighted valve, and wait for it to return to zero before putting it on the scale. Repeat three times to see if these values are the same. It also depends on whether it can stabilize quickly, whether the value is large, and whether it can stabilize quickly.
Meeting the above conditions is qualified, and a better balance, which is suitable for purchase. I think if the budget is limited, there is no need to worry about any brand. Many domestic balances also performed well.
