Impedance Meter With Lead Selector
The "ES" includes a switch and associated circuitry to select up to 22 separate electrode leads. This allows the 1089 ES to be used to RAPIDLY and PAINLESSLY check applied electrode contact impedance of multiple electrode configurations such as Cranial EEG "caps".
4mm Adhesive Collars
These 4mm double-sided adhesive collars are used to hold reusable electrodes firmly on the skin surface.
