Veidt Weighing is a Electronic Balance factory in china. Electronic balance as an indispensable precision weighing instrument in modern laboratories and industrial fields, is based on the principle of electromagnetic force balance in its core technology. When the sample is placed on the weighing plate, the downward force generated by gravity will be balanced by the reverse electromagnetic force generated by the internal electromagnetic coil. This process is converted into electrical signals through precision sensors, and then processed by a microprocessor to display the weighing results in digital form.

A standard electronic balance consists of the following key components:

Weighing tray: usually made of stainless steel, used to place the item to be tested
Electromagnetic force compensation system: core weighing mechanism
Analog to Digital Converter (ADC): converts analog signals into digital signals
Microprocessors: responsible for data processing and computation
Display screen: Intuitively display the weighing results
Shell and windproof cover: protect internal components and reduce environmental impact

Modern Electronic Balances have multiple advanced technological features:

Resolution and accuracy: High end laboratory scales can reach 0.0001g (0.1mg) or even higher
Weighing range: ranging from milligram level microbalance to kilogram level industrial balance
Calibration method: automatic calibration with built-in weights or manual calibration with external weights
Environmental adaptation: Temperature compensation technology ensures accuracy in different environments
Data transmission: USB, RS232 or Bluetooth interfaces for data output
Multifunctional: equipped with additional functions such as counting, percentage weighing, density measurement, etc

According to accuracy and purpose, Electronic Balances are mainly divided into the following categories:

Analytical balance (accuracy 0.1mg-0.0mg):
Applications: Laboratory quantitative analysis, drug development, chemical experiments
Features: Usually equipped with windproof cover, high sensitivity

Precision balance (accuracy 1mg-0.1mg):
Application: Industrial production quality control, educational experiments
Features: Durable and sturdy, with a wide weighing range

Micro/Ultra Micro Balance (Accuracy 0.001mg and below):
Application: Nanomaterial research, trace analysis
Characteristics: Extremely sensitive, requiring a special seismic platform

Industrial balance:
Application: Production line, warehousing and logistics
Features: Large weighing range, high protection level

To ensure the accuracy and service life of Electronic Balances, the following operating procedures should be followed:

Installation environment selection:
A stable workbench to avoid vibration
Stay away from air conditioning vents and direct sunlight
An environment with minimal temperature fluctuations (preferably 15-25 ℃)

Daily usage precautions:
Preheat for more than 30 minutes after startup (more time required for high-precision scales)
Regularly calibrate (especially after changes in usage environment)
Close the windproof door during weighing to avoid the influence of airflow
Handle the sample gently to avoid impacting the weighing plate

Maintenance and upkeep:
Regularly clean the weighing tray and housing
Keep powered on when not in use (avoid frequent switching)
Long term disuse should remove the battery
Regular calibration by professional personnel

Electronic Balances have evolved from simple weighing tools to high-tech instruments that integrate precision measurement, data analysis, and process control. They play an irreplaceable role in precise measurement in scientific research, industrial production, medical and pharmaceutical fields. Choosing, using, and maintaining Electronic Balances correctly will ensure reliable data support and provide a solid foundation for all work.
