This is multi-purpose Ag/AgCl electrode conductivity gel. It is highly conductive, chloride free and hypoallergenic. Its non-thinning formula will not irritate and will resist breakdown from body heat and salts in perspiration and will remain moist, thick and uniformly conductive throughout the most prolonged polygraph examination. This gel reduces the electrode-impedance and optimizes the contact between the skin and the electrode thus leading to better quality parameter tracings. This electrode gel can be used with the three models (stainless steel and disposable) of EDA Electrodes offered by Lafayette Instrument Company.
