TS Testing Sensor
Simple identifier of electrochemical hardware error
Dimensions: 25.4 x 7.26 x 0.63 mm
Electrochemical measurements are very sensitive. Sometimes cables, connectors and their wetness can create the measurement errors. Testing sensor enables simple identification of electrochemical hardware error. The sensor has same geometry as AC1 type but its response produced by resistor. The response is stable and independent on chemistry. Testing sensor is formed on a corundum ceramic base. At the end of the sensor there is a contacting field which is connected with the SMD resistors by the silver conducting paths which are covered by a dielectric protection layer.

FC2.TL.* PMMA Flow Cell
Read moreThe flow cell enables the use of Screen printed sensors in a flow through arrangement.
The flow cell is suitable for sensors of type AC1, AC2, CC1, CC2 and CC3.
The Screen printed sensor is inserted into the slit of cell and tightened by closing of the door. The cell ensures the wall-jet flow around the working electrode and it is optimised so that no air bubbles cumulate in the cell. The cell contains also the contact and output cable.
With the sensors enclosed in a flow cell, it is possible to measure semi-automatically or automatically using a pump or liquid switch for sample supply. Under such conditions, maximum measurement reproducibility is ensured.
