How to choose an electronic balance?

Noble Mall's main laboratory equipment, agent METTLER TOLEDO, Sartorius, Ohaus, Jingke, Liangping, Longteng electronic balance, all kinds of parameters are available.

The selection of electronic balance is mainly based on: range, accuracy, brand, performance and price.

1, range

That is, the weighing range of the balance, the range is divided into single range and double range.

Single-range means that the accuracy value is constant within a certain accuracy range.

Dual range means that the accuracy value can be changed within a certain accuracy range, such as: 0-41g, the accuracy value is 0.01mg, and the precision between 41-220g is 0.1mg.

2, the accuracy value

Refers to the accuracy of the balance reading during the weighing process, commonly used 0.01mg, 0.1mg, 1mg, 0.01g and so on.

3. Brand:

METTLER: The world's number one brand, produced in Switzerland, with good stability and high price, suitable for high-end laboratories, such as the national quality inspection department.

Ohaus: Acquired by METTLER, its technical application of METTLER, with METTLER in a production line, the quality is better, better stability, higher cost performance, welcomed by various domestic industries. Suitable for medium and high-end laboratories.

Sartorius: second only to METTLER, for high-end laboratories.

Shanghai Jingke: a well-known domestic brand with good stability and suitable for mid-range laboratories.

Shanghai Liang Ping: Domestic famous brand, high price, good after-sales, high visibility.

Shenyang Longteng: domestic famous brand, well-known brand, the main high-end laboratory, the price is more expensive.

Shanghai Yueping: Domestic famous brand, high cost performance, complete model.

4, performance:

The balance is divided into inner school balance and external school balance

The external school balance refers to the manual weight calibration according to the specified operation when the weighing value or the calibration value is unstable.

The internal school balance refers to the standard weight inside the balance instrument, the system automatically one-button internal school, eliminating the cumbersome manual weight, improving the efficiency and accuracy of the experiment.

5, the price:

Choose the model based on the customer's budget. The instrument is divided into domestic and imported categories.

Domestically produced machines include instruments produced by domestic brands and domestically assembled machines. Prices range from 4000-20000.

The imported machine mainly refers to the instrument imported from the original machine. Prices range from 10,000 to 100,000.
