What are the specifications of the laboratory balance room?
Analytical balances are one of the most important instruments in quantitative analysis. Before starting the analytical work, you must be familiar with how to use the analytical balance correctly, because the accuracy of the weighing has a great influence on the analysis results. Commonly used analytical balances have semi-automatic electro-optical balances, automatic error correction analytical
Operating guidelines for precision electronic balances
The electric scale precision balance belongs to the electronic balance with high precision in the electronic balance. The instrument is equipped with high-precision weighing, so the accuracy and reaction speed of the instrument are very high. The precision electronic balance is widely used in research institutes, laboratories, etc. To do quantitative analysis.
Failure of balance sensitivity to reach technical index
Analytical Balance Manufacturer introduces the fault phenomenon that the sensitivity cannot reach the technical index Failure of balance sensitivity to reach technical index.
The failure phenomena, influencing factors and adjustment methods of the balance whose sensitivity cannot reach the technical index are as follows:
How to calibrate and install the 0.0001g scale?
1. Ensure stable, vibration-free placement and as horizontal as possible.
2. Avoid direct sunlight, strong temperature changes and air convection. It should be placed on a stable counter in the corner of the room and protected from airflow from doors, Windows, radiators or air-conditioning vents.
The efficiency and accuracy of electronic balance
The electronic balance produced is reasonably designed and reliable weighing results can be obtained in laboratories and workshops under normal conditions. But choosing the right setting environment can improve the work efficiency and the accuracy of measurement results.
Analysis of the reasons why electronic balances do not display weighing data
1. The sample has properties of water absorption, water discharge, electrostatic and magnetic. The correct use of weighing and microbalance can only be achieved by overcoming the above influences.
A description of the linear accuracy of the one-thousandth electronic balance
Stability can be divided into long-term stability and instantaneous stability. Long-term stability means that the environmental temperature of the electronic balance does not change much, while instantaneous stability means that the value displayed by the balance is displayed immediately and remains unchanged after the balance is placed on the measured object.
The halogen moisture meter is introduced in detail
Moisture Analyzer is the general term for all instruments used to measure moisture content. It is mainly used to measure the moisture content in solids, liquids and pastes. According to different test principles, we can be divided into a variety of, among which the most common include halogen moisture meter.
Maintenance of electronic precision balance
1. Place the balance on a stable work table to avoid vibration, air flow and sunlight.
Electronic balance fault repair method
Resistance method: first test whether the resistance between E+E- and S+S- is close to its nominal value. If normal, you can also measure the resistance between E+S+ and E+S-, which should usually be the same or close (the difference is more than 2 ohms and basically there is something wrong with the sensor).
