Sampling 10 or 100 data per second in a high speed, recording each voltage and current change accurately.

In the field of electrochemical research and battery testing, researchers (students) pay more attention to the potential difference between the working electrode (or auxiliary electrode) and the reference electrode while paying attention to the pressure difference between the working electrode and the auxiliary electrode. The auxiliary channel binding method is adopted to isolate from the main channel without interference, and the data is transmitted synchronously (sampling interval), so as to ensure the accuracy and consistency in the battery tests.

Via different current discharging, we can get the rate performance.

The design of the μA current unit plays a vital role in the field of current accurate measurement, which is more convenient and more accurate. Generally, magnetoelectric galvanometer can achieve μA level, electromagnetic galvanometer can achieve mA level. 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.

dQ/dV Differential capacity curve: Where there is a peak on the curve meaning the charge and discharge curves have a voltage platform, and different peaks represent different electrochemical reactions.dQm/dV Differential specific capacity curve:dQ/Active material quality/dV.

电池的内阻作为锂电池的关键特性之一，是影响锂电池功率性能和放电效率的重要因素， 是衡量锂电池功率性能和评估锂电池寿命的重要参数。测试方法，给电池施加一个短时电流脉冲，测量其端电压与开路电压的差。用这个差值除以测试电流即认为是电池的直流内阻。软件的设计支持不同的测试方法和不同数据取值方法，兼容性强，可根据需求进行设置计算。

Ultra-lightweight appearance, pro-inspired features, dQ/dV curve，multi-range，0.01% accuracy, and three-electrode system test.

To meet the various requirements adopted in advanced battery research, our equipments can automatically switch the current range in accordance with user settings to maintain consistent accuracy, and can be fitted with additional hardware to provide a number of optional features and capabilities.

Generally, the reaction time is divided into two parts: rise time (rise time ≤ 500 μ s) and fall time (fall time ≤ 500 μ s), and the sum of the two parts shall prevail.
