Two versions of this high performance AC amplifier feature high gain, adjustable filters, low noise and an output which is easily interfaced with peripheral devices such as computers, oscilloscopes and recorders. All models require an external power supply.

For low impedance electrodes, connection may be made directly to the P511 via the standard input cable supplied. An optional high impedance probe provides an excellent interface for high impedance microelectrodes.

All models are CSA/UL listed for medical device safety.

MODELS P511 & CP511

The Model P511 has been the neurophysiologists' workhorse for extracellular recordings from nerve and muscle for years. EMG, EEG, ECG and ERG are just a few of the types of signals that can be recorded using the P511. The P511 is packaged as a 19" rackmountable amplifier, 1.75" high.

The CP511 shares all of the superior features with the P511, but is packaged for portable bench-top use. The unit is enclosed in a compact, rugged all-metal cabinet that is easy to stack vertically or horizontally. Optional rackmount hardware allows two units to be mounted side-by-side in a standard 19" rack while using only 3.5" of vertical space.

An optional, very low leakage input cable is available for additional safety in high-risk environments. The cable features less than 3 µA leakage current at 120 VAC, 60 Hz (for use with P511 and CP511 only).
