Introduction 

 
The Model 2122 is a differential amplifier for use with low-
level signals -- 2 microvolts and above -- ranging from DC 
to 10 KHz.  Primarily designed as biological 
instrumentation, the Model 2122 is well suited to many 
other demanding applications.  It features high common-
mode rejection, high input impedance, low noise, small 
size, and excellent frequency response.  The Model 2122i 
includes subject isolation, but is otherwise identical to the 
standard Model 2122.   A BioAmplifier Input Box with 
convenient binding post terminals is an included accessory.
