Sensit Smart
智能手機恆電位儀，Sensit Smart 是市場上最小的即用型恆電位儀， 可以直接插入智能手機或平板電腦，並通過 Android 應用程序PStouch 進行控制。
我要諮詢智能手機恆電位儀，Sensit Smart 是市場上最小的即用型恆電位儀， 可以直接插入智能手機或平板電腦，並通過 Android 應用程序PStouch 進行控制；您可以使用 USB-C 母頭轉 USB-A 電纜將 Sensit Smart 連接到 PC USB 端口，並通過我們的 PC 軟體PSTrace控制 Sensit Smart ，能夠進行高達 200 kHz 的 EIS，電位範圍 -1.7 至 +2 V，電流範圍 100 nA – 5 mA（最大 ±3 mA）
The Sensit Smart works at three different modes;
- Low Speed mode: for scan rates up to 1 V/s or a bandwidth of 100 Hz.
- High Speed mode: for high scan rates and frequencies.
- Max Range mode: a combination of the Low and High Speed modes for optimal dynamic dc-potential range.
| Low Speed mode | High Speed mode | Max Range mode | |
|---|---|---|---|
| General | |||
| Full dc-potential range | -1.2 to +2 V | -1.7 to +2 V | -1.7 to +2 V |
| Dynamic dc-potential range[1] | 2.2 V | 1.2 V | 2.6 V |
| Compliance voltage | -2.0 to +2.3 V [2] | ||
| Maximum current | ± 3 mA | ||
| Max. acquisition rate (datapoints/s) |
100 | 1000 | 100 |

| Current accuracy | < 0.5 % of the selected current range < 2% for 100 nA current range |
< 1% of the selected current range | < 1% of the selected current range |
| Measured current resolution | 0.006% of selected current range (5.5 pA on 100 nA range) | ||
| Measured potential resolution | 56 uV | ||
FRA / EIS (impedance measurements)
| Frequency range | 0.016 Hz to 200 kHz |
| Ac-amplitude range | 1 mV to 0.25 V rms, or 0.708 V p-p |
[1] The dynamic range is the range that can be covered during a single scan within the full potential range. For example; a linear scan can start at -1.5 V and end at 1.1 V or vice versa, covering 2.6 V dynamic range.
[2]The compliance voltage is the maximum potential between Working and Counter electrode and depends on the selected mode.
