Neware TWS LIR1654 Button Battery Cycle Tester Rechargeable Battery Test Machine
1 . Sensitive galvanometer is used for students to check weak current or tiny voltage in DC circuit in the lab . It is a kind of high sensitive magnetoelectric instrument , which can measure the tiny current .
2 . dQ / dV differential capacity curve , the peak on the curve indicates that there is a voltage plateau on the charge and discharge curve , and different peaks represent different electrochemical reactions .
3 . The design of the uA current unit plays a vital role in the field of current accurate measurement , which is more convenient and more accurate .
4 . The lower range is able to output current low as 5uA , which can tell the subtle difference of various materials such electrodes , electrolyte , separator , etc .
5 . Generally , magnetoelectric galvanometer can achieve uA level , electromagnetic galvanometer can achieve mA level .
