The Sensit BT is ideal for electrochemical sensor applicatons. The Sensit BT is designed for use with screen-printed electrodes and is available in a re-branded housing for OEM purposes. The Sensit Smart is built around the proven and calibrated EmStat Pico module, which is a joint development by Analog Devices and PalmSens.
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).
Two versions:
Sensit BT.SPE | Sensit BT.SNS | ||
| Sensor pitch | 2.54 mm | Cable length | 40 cm |
| Electrode connections | RE, WE, CE | Connectors | 2 mm banana |
| Allowed sensor thickness | Between 0.1 mm and 0.8 mm | Electrode connections | RE, WE, WE2, CE |
| Maximum sensor width | 11 mm | ||
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.

Specifications
The Sensit BT works at three different modes;

[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.
