Description

The Sensit BT is ideal for electrochemical sensor applications. 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 wirelessly 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 / Custom 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  
Customize the Sensit BT for your sensor
If your sensor has 4 electrodes or more, PalmSens can customize the Sensit BT to fit your sensor. For example a sensor with two working electrodes: RE, WE1, CE, WE2.

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 working electrodes 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.

Techniques

Voltammetric techniques

Linear Sweep Voltammetry (LSV)
In Linear Sweep Voltammetry a potential scan is performed from the begin potential, to the end potential. The voltage during the scan increases with small potential steps. Continue reading
Cyclic Voltammetry (CV)
Cyclic voltammetry is a known method of demonstrating the presence of a substance in a given liquid by drawing a graph with a characteristic wavy line. Continue reading

Pulsed techniques

Differential Pulse Voltammetry (DPV)
In Differential Pulse Voltammetry a potential scan is made using pulses with a constant amplitude of E pulse superimposed on the dc-potential. Continue reading
Square Wave Voltammetry (SWV)
Square Wave Voltammetry is a special version of Differential Pulse Voltammetry is, where the pulse time is equal to half the interval time. Continue reading
Normal Pulse Voltammetry (NPV)
In Normal Pulse Voltammetry (NPV) a potential scan is made by making constantly larger potential steps of pulse. Continue reading

Amperometric techniques

Chronoamperometry (CA)
The instrument applies a constant dc-potential and the current is measured with constant interval times. Continue reading
Chronocoulometry (CC)
Chronocoulometry is an electrochemical technique during which a potential is set. Continue reading
MultiStep Amperometry (MA)
MultiStep Amperometry (MA) is an electrochemical technique which simply allows the user to specify the number of potential steps they want to apply and how long each step should last. Continue reading
Pulsed Amperometric Detection (PAD)
With Pulsed Amperometric Detection a series of pulses (pulse profile) is periodically repeated. Pulsed Amperometric Detection can be used when higher sensitivity is required. Continue reading

Potentiometric techniques

Open Circuit Potentiometry (OCP)
Open Circuit Potential (OCP) is the potential where no current is flowing, because the circuit is open. Continue reading

Impedimetric techniques

Potentiostatic Electrochemical Impedance Spectroscopy
(PEIS)
During a conventional EIS (PEIS) a potential sine wave is applied and the resulting current is measured. Continue reading
DC-potential sweep
The Impedance is measured at a fixed frequency, varying the DC-potential (also called DC-Bias or DC-level). This setup is the same as for Mott-Schottky, but currently our software doesn't support data plotting as required for Mott-Schottky.
Impedance time scan
The Impedance is measured versus time, at a fixed frequency. Continue reading

Other

Mixed Mode (MM)
Mixed Mode is a flexible technique that allows for switching between potentiostatic, galvanostatic, and open circuit measurements during a single run. Continue reading
Custom techniques (MethodSCRIPT)
MethodSCRIPT gives you full control over the instrument. It allows you to customize and combine measurement techniques and perform actions including using on-board storage, data analysis and controlling external peripherals. Continue reading
BiPotentiostat techniques
Refer to our BiPotentiostat article to check which techniques are available when using BiPotentiostat mode. Continue reading

Overview of software development tools

Software Development Kits for .NET

The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.

PalmSens SDKs with examples are available for the following .NET Frameworks:

  • WinForms
  • WPF
  • Xamarin (for Android)
  • UWP
SDKs for .NET

MethodSCRIPT™ communications protocol

The Sensit Series have an on-board parser for the MethodSCRIPT scripting language. This language allows developers to program a human-readable script for the Sensit Series on any platform or operating system. The simple script language allows for running electrochemical techniques supported by the Sensit Series and makes it easy to combine different measurements and other tasks.
