In the process of analyzing the balance, we encounter various technical problems. Next, we will answer a few questions with relatively high questioning rates, and there are definitely some questions you want to ask!
First, the laboratory must set up a special balance room to place one 0.001g precision balance? Can it be placed directly on the separate platform in the inspection room?
The environmental conditions of this level of balance are generally not more than 30 degrees Celsius, the humidity is not more than 85%, and the temperature difference during operation does not exceed 5 degrees Celsius; but whether it can be placed directly into the test room alone should also consider whether the room is There are corrosive gases, vibrations, and airflow effects that can be placed if they are all satisfied.
Second, should the silicone in the electronic balance be replaced regularly and how often?
Experts suggest that do not put desiccant in the balance, to control the temperature and humidity between the balance. If you really want to let it go, it will be changed according to the actual situation.
Third, how does an electronic balance school?
1, the balance should be warmed up, the time is about 2-3 hours
2, the balance should be horizontal, otherwise it will be adjusted
3, when the balance is said to have no weighing objects, it should be displayed in a stable position.
4, press the “CAL” button to start the internal calibration function of the balance. Later, the electronic balance displays “C”, indicating that the internal calibration is in progress.
5, when the electronic balance display shows zero position, the electronic balance should be calibrated.
Fourth, how is an electronic balance school?
1, the balance should be warmed up for more than 30 minutes
2, the balance should be in a horizontal state
3, when the balance is not weighing, the scale should be stable to zero.
4, press the “CAL” button to start the calibration function of the balance.
5, the weight value of the external correction weight is displayed on the display of the balance.
6, place the standard weight that meets the accuracy requirements on the scale of the balance.
7, when the display value of the electronic balance is unchanged, it indicates that the external calibration work has been completed, and the standard weight can be taken out.
8, the balance shows that the zero position is inactive.
If an error occurs during calibration, the electronic balance display will show “Err”, the display time is very short, it should be reset again, and the calibration will be performed again.
Lab Electronic Balance
Fifth, what are the balances of different precision levels used for?
1, lower precision, process preparation test
2, one thousandth, do the technical test
3, one in ten thousand, do the above test and chemical analysis test
4, one in 100,000, do instrument analysis
5, higher precision balance, one in a million, for instrumental analysis
Sixth, in order to control the temperature and humidity, it is inevitable to open an air conditioner or a fan in the summer. How to avoid the impact of the wind on the balance?
1, the balance should be placed in the laboratory away from doors and windows.
2, when there are multiple balances, the more precise the balance should be placed inside the balance
3, it is best to install a glass windproof door for the analysis balance. The micro/ultra-micro balance with high precision even needs two layers of windproof doors.
We also provide customized electronic balances/ laboratory scales with special functions according to customer needs.
