Sensit BT

The Sensit BT is ideal for electrochemical sensor applications. It connects via Bluetooth to your smartphone or tablet. From there you can control it using the Android app, PStouch. You can use the USB-C port to charge the sensit BT or connect it to a normal USB port on your PC. From there you can control it using PStrace software .

In brief:

  • Capable of EIS up to 200kHz
  • Potential range -1.7 to +2V
  • Current ranges 100 nA – 5 mA (max ±3 mA)

Two Versions:

The Sensit BT.SPE can be used for running sequential measurements on two different Screen-Printed electrodes (SPE’s) with their own Reference, Counter and Working, Electrodes.

The second channel can also be used in Bipotentiostat mode, which would be functioning as the second Working Electrode versus the Reference, and the Counter, Electrode channel 1. Both Working electrodes will be recorded at the same time in the Bipotentiostat mode.

The Sensit BT.SNS has a lead connected to the WE of channel 2 and this can be used out of the box for BiPotentiostat measurements.
