Sensit BT

The Sensit BT is ideal for electrochemical sensor applications. The Sensit BT connects via Bluetooth to your smartphone or tablet and controlled via the Android app PStouch. You can use the USB-C port to charge the Sensit BT or connect to a classic USB port on your PC and control the Sensit BT via our PC software PSTrace.

The Sensit BT supports most common electrochemical techniques, including Cyclic Voltammetry, Square Wave Voltammetry and Impedance Spectroscopy (FRA/EIS).

Dual-channel and Bipotentiostat

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

The second channel can also be used in Bipotentiostat mode, functioning as second Working Electrode versus the Reference and Counter electrode of channel 1. Both channels are recorded simultaneously in the Bipotentiostat mode.

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

On-board data storage

The Sensit BT is equipped with 500 MB internal storage memory.

Save measurements on-board as a backup. Or pre-program the device with a script and use the trigger button to run and store measurements: no need to connect a PC or smartphone. Browse and transfer all internally stored measurements back to the PC easily using PSTrace for Windows.

(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.
