EEG electrode D01.5H03

reusable

Silver/silver chloride (Ag-AgCl) is recognized worldwide as a stable, low noise reference electrode. It is reversible, which means it can pass an electric current without changing the chemical environment in the immediate vicinity of the electrode. These sensors are less prone to artifact than metal electrodes. Greentek pellet sintered silver/silver chloride (Ag/AgCl) electrodes are made from very finely powdered high purity silver and silver chloride. They are mixed in a specific ratio and compacted into the electrode body at very high pressures. The resulting pellet is relatively thick (1.5mm to 2.0mm) and never needs to be re-chloridized because it is a homogenous. Greentek pellet sintered Ag-AgCl electrodes incorporate a variety of features which improve biopotential recordings: • Fine grain, homogeneous mixture of Silver-Silver Chloride • Sintered to increase electrode/electrolyte contact area • Reusable via resurfacing or re-shaping by sanding, cutting, drilling and filing • Non-polarizable • Do not require chloriding Technical Parameters: • AC impedance: ≤25 Ω.cm²(10Hz) • DC Offset electric potential: ≤180 µV • Potential drift: ≤180 µV per hour • Noise: peak value ≤1 µV(1Hz) Features * High precision, low noise, low impedance * The only material that meet the requirement of the event-related potentials measurement * technological patent for invention, ISO 13485, CE, Rohs certificated * Custom made for specific requirements
