  1. W&J Best Quality Analytical Balance Factory,Good product quality, reasonable price and high cost performance

  2. W&J brand new automatic internal school analytical balance has a large touch color screen, five-sided fully transparent glass windshield. Using a new generation of electromagnetic force sensor, stable performance, small error. The balance has functions such as counting, multi-unit conversion, tare, zero tracking and so on. Fully automatic internal calibration, simple operation. Built-in RS232 or USB interface, you can connect to computers, printers and other equipment.


The scale mainly works on the principle of force deformation of electronic strain elements. When an object is placed on the scale pan, pressure is applied to the sensor, and the sensor undergoes elastic deformation, thereby changing the impedance, and at the same time, the excitation voltage changes, outputting a changing analog signal. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter, converted into a digital signal that is easy to process, and finally output to the CPU for calculation control, and the result is displayed on the display.

    • How to use the scale‌: ‌Place the scale‌: Make sure the scale is placed on a stable and level ground to avoid measurement errors caused by unevenness. ‌Power on‌: Press the power switch and wait for the scale to complete the self-check and display the zero point. ‌Place items‌: Place the items to be weighed in the center of the scale pan to avoid tilting or offset to ensure accurate measurement. ‌Read data‌: The scale will automatically display the weight of the item, and the displayed number can be read directly. If more precise measurement is required, a standard weight of known weight can be placed on the scale pan for calibration. ‌Power off‌: After weighing, press the power switch to turn off the scale. ‌ ‌

    • Maintenance and Care‌:

    • ‌Regular Calibration‌: Use standard weights to calibrate the scale regularly to ensure measurement accuracy.

    • ‌Cleaning and Maintenance‌: Use a soft cloth to wipe the scale pan and housing. Avoid using a wet cloth or chemical solvents to prevent damage to the surface or internal components.

    • ‌Moisture and Dustproof‌: Avoid using the scale in a humid or dusty environment to prevent affecting the measurement accuracy and equipment life.
