Model 15LT Bipolar
High Impedance Input, Electrode Selector

HIGH IMPEDANCE INPUT MODULES

Two optional High Impedance Input Modules are available for microelectrode applications,

The Model HZP single-channel probe also incorporates a switching circuit that provides selection of either recording or stimulating through the same electrode.

The 15BIHIP Bipolar High Impedance Probe is a compact accessory module designed to preserve the frequency response characteristics of Grass Model 15 Neurodata Acquisition System when interfaced with high impedance electrodes. The module improves the input characteristics when microelectrodes are used.


MODEL 15ES3 MINIATURE ELECTRODE SELECTOR

The Model 15ES3 features 19-position electrode selection for each of 8 channels. The remaining 8 channels are dedicated bipolar channels. The 15ES3 features small size and uses DIP switches for electrode selection. It is ideal for portable applications utilizing the 15LT unit.
