The AELAB JA Series Analytical Balance is engineered for high-precision weight measurement in laboratories, offering 0.001g readability. With automatic calibration, electromagnetic sensing, and intuitive operation, it ensures reliability and accuracy for critical scientific applications.
Analytical Balance is designed for precise measurement of small sample weights. It features automatic calibration, an advanced electromagnetic force sensor, and a clear LCD display with a white backlight. Key functions include tare, counting, unit conversion, density measurement, and dynamic weighing. The balance also supports printing, has overload and fault alarms, and optional accessories such as density kits and USB connectivity. It is perfect for laboratory applications requiring high accuracy and reliability.
FEATURE
1.Electromagnetic sensor
2.AA-N (intemal calibration]
3.Aluminum shell large space wind proofcover
4.LCD[white back llght with black font]
5.Tare functiony Counting/unit conerslo(g/mg’ct/oz…)
6.Sensitivity/Speed set/Percentage
7.Overload alarm/Fault alarm/evel indlcator
8.Option:Under welghing/Pnnter
The AELAB JA Series Analytical Balance uses an electromagnetic force sensor to detect micro-changes in weight. When a sample is placed on the weighing pan, the sensor generates a magnetic field that balances the load. This force is then converted into a digital signal, accurately displayed on the LCD. The internal or external calibration systems ensure precise results even with environmental changes.
