Flexible three-electrode gold electrode The reference electrode is silver/silver chloride. The working electrode and the counter electrode are gold.

Single-channel three-electrode screen printing electrode and electrode connector and serial port usb portable detection module

Working electrode: it can be platinum, gold, silver.
Counter electrode: It can be platinum, gold, or silver.
Reference electrode: It can be platinum, gold, silver/silver chloride.
In addition, the electrode interface seat can be customized according to different electrodes, which is convenient to connect to the electrochemical workstation of the test system.
If you need a three-electrode two-electrode test module, you can also contact me, and adjust the current to be tested according to your polarization voltage requirements.
Provide 20na precision 0.01na small current detection module. This module can realize constant voltage detection timing current. Amplify the small current in real time
, Filtering, i/v conversion to form a PWM frequency signal that can be transmitted over a long distance. The greater the current, the greater the corresponding voltage, and the output of the module
The faster the frequency. It is convenient for students who can use single-chip microcomputer to carry out the later system development.
If you don’t know how to develop a single-chip microcomputer system, I can also provide a complete test and display platform, which can display the current size you detect in real time on the display, EEG or mobile phone. .
I wish my friends a smooth journey on the road of scientific research!

Screen-Printed Sensor
Technical Data Sheet
Rev.B, 18
Product Description
The sensor of 3-electrode system is made by SPE technology on PET substrate(0.25mm). On the
surface of electrodes, rare metal (Au) and Ag/AgCl were decorated on working/counter electrode and
reference electrode, separately. The contact pad on sensor also covered by gold for corrosion
prevention. The bio-chemical active species such as enzyme and/or mediators can be immobilized
directly on working electrode to act as biosensor. A simple Cyclic voltammetry (CV) test of
Ferricyanide(50mM)/KCl(10mM) solution on this product was carried out and high response current
was obtained as below:
Application:
Electrolysis, heavy metal detection, glucose/lactate biosensor, DNA/immunosensor, uric acid
detection, electrochemiluminescence immunosensing
Storage:
Disposable sensor must be kept at humidity below 30%RH and ambient temperature near 20℃away
from sunlight.

Wiring instructions for circuit board and shock head (ceramic plate transducer) :

1. Shock head two wiring, two ceramic pieces of the middle of the wiring piece for the positive pole, by the upper and lower metal column for the negative pole, remember not to connect the reverse;

2. The silver-coated side of the ceramic plate of the transducer is a negative electrode, while the larger side of the other two silver layers is a positive electrode, and the smaller side is a negative plate. When welding the power cord, it must be welded on the side with two silver layers, and the other side is a vibrating surface, which can be pasted under the washing basin (this is the component description of the ceramic plate transducer purchased). The silver layer on the ceramic plate is not resistant to high temperature. When welding the power line, the temperature of the soldering iron shall not exceed 280 degrees. It is better to use the constant temperature soldering iron and set the soldering iron temperature as 250 degrees.

3. The larger side of the shock head (with a screw hole) is the shock surface that can be glued to the bottom of the cleaning basin. The cleaning basin should be grounded reliably.

4. Shock head or transducer ceramic plate application shock head glue firm paste on the bottom of the cleaning basin, can also be used AB adhesive paste, but the effect is slightly poor, such as using epoxy resin ratio of 10:4 can be;
