Low Profile Ag/AgCl Electrode, 8mm sensor diameter with Hole (to inject gel), 100cm lead wire, terminates in 1.5mm touch-proof (TP) connector. Can be used for various applications including EEG, EMG, facial EMG, EOG.

These Ag/AgCl Sintered Electrode come with a 1mm thick Ag/AgCl electrode sensor mounted in a durable epoxy ring housing. This housing is of a "Low Profile" meaning the height of the housing is 5mm. The epoxy coating of the housing ensures durability and a waterproof electrode. Additionally, this electrode features a hole through the electrode for injecting a conductive gel. The diameter of the Ag/AgCl sintered electrodes with low profile and hole come is 8mm. Packaging size is one Ag/AgCl sintered electrode per pack.

Ag/AgCl sintered electrodes feature a small cavity that should be filled with a conductive gel, cream, or paste. The depth of the cavity is 2mm.

This Ag/AgCl sintered electrode can be re-used when treated with care and cold sterilized after use. The lead wire length is 100cm (40”) and terminates in a DIN 1.5mm touch-proof (TP) connector. Standard lead wires are PVC insulated multi-strand copper with internal Tinsel for additional strength and durability.

These versatile Ag/AgCl sintered electrodes have the consistency of soft metal and can be re-shaped by sanding, cutting, drilling and filing. Designed for use in electrochemistry, stimulation, precision bioelectric recording, electrophysiology and neurophysiological applications.

Ag/AgCl sintered electrodes can be used as both standard and reference electrodes, due to their stability and reproducible results. Silver-Silver Chloride (Ag/AgCl) Electrodes are known for their low offset voltage, low noise and stability. Reusable and non-toxic, the electrodes can be cold sterilized and used for many years with minimal care.
