JASeries electronic precision balance
Product Introduction:
JA1003The electronic precision balance adopts the principle of electromagnetic force balance, and its heavy sensor has the best mechanical quality to ensure the accuracy of its reading. The interface menu is displayed directly on the panel in an open mode, and the operation is simple and fast. It has strong anti electromagnetic interference ability and anti-static protection functions.
JA1003Electronic precision balance can be applied to the analysis industry,metallurgy,Coal mining, food, college and other fields. Horizontal adjustment of orientation, using a precise level and adjusting feet to ensure accuracy in the balance reading.

Environmental requirements:
supportJA1003The electronic precision balance is placed on a stable workbench to avoid vibration and airflow.
Working environment temperature:IThe scale is20℃±2.5℃The temperature fluctuation is not greater than1℃/Hour;
IIThe scale is20℃±7.5℃The temperature fluctuation is not greater than5℃/Hour.
Relative humidity of the environment:IThe scale is50%~75%;
IIThe scale is40%~80%.
matters needing attention:
In order to obtain accurate measurement values,Ⅰ Grade scale(JAThe series requires one hour of preheating when the power is turned on, and the balance should be preloaded and calibrated before use (when weighing has not been performed for more than an hour).
