Ag-AgCl Electrode – 12mm Sensor with 1 meter leadwire – low profile. These sintered Silver-Silver Chloride (Ag/AgCl) electrodes incorporate a fine grain, homogeneous mixture of Silver and Silver Chloride compressed and sintered to strengthen and stabilize. They are reusable, resurfaceable, never need rechloriding and are essentially non-polarizable. Sintered Ag/AgCl electrodes are known for their low offset voltage, low noise and stability and can be used indefinitely with minimal care. Electrodes are 1mm thick, encapsulated in durable housings and come with 1m (40 inch long) PVC insulated lead wires terminated with a 1.5mm DIN safety socket. Available with the following lead wire colors: White, Red, Brown, Black, Green & Blue (please specify if you have a preference when ordering). Electrical Specifications: Typical values of the key parameters, measured in 0.9% saline, between pairs of Ag-AgCl electrodes of the same size DC offset Voltage: 180 V, Drift: 25 V/hr, Noise: 1 V p-p (0.1-1 kHz with 50 Hz eliminated).
