Model 15ES1 Electrode Selector Series
Several Electrode Selector units are available for applications requiring independent electrode selection from a remote site. These modular electrode selectors are precious metal mechanical pushbutton switch assemblies featuring time proven reliability. The 15ES1 series provides 23 selectable positions and are available in both Numeric and International nomenclature. 4-, 8-, 12-, and 16-channel sizes are available and all rack-mount in 8.75" (22.2 cm) vertical space. All cabling is provided including companion electrode boards, and input cables. For multiple animal recordings requiring more than the 23 total electrodes, a special "split" version of the 15ES1-16 is offered. This unit provides full 23 electrode positions to each bank of four amplifiers. The additonal electrode boards and input cables are included with this special version.

Model 15ES2 Electrode Selector Series
The Model 15ES2 is designed for sleep recording applications. The 15ES2-16 provides 19 selectable positions for each of the first eight channels in Numeric nomenclature only. The remaining eight channels are dedicated bipolar positions with no electrode selection and are intended for bipolar electrode derivations, and various transducers and sensors. This unit is for single-bed polysomnography applications. The 15ES2-32 provides 19 selectable positions for each of 16 channels and the remaining 16 channels, 9-16, and 25-32 are dedicated bipolar channels with no electrode selection. This unit is intended for two-subject sleep recordings. The 15ES2 requires 8.75" (22.2 cm) vertical space for rackmounting. Electrode boards and input cables are included.

The REFM15 kit converts the Model 15 bipolar input system to a referential input system used in many EEG applications. Conversion includes the electrode board, input cable and a referential montage card. These are modular items and easily replace the bipolar components.
