Bio-Amplifier

Description

Product category: Phipps and bird.

The Bio-Amplifler is a low noise differential amplifier with a maximum gain of 5000. The
Bio-Amplifier allows views of bioelectric potentials in the microvolt range (10 μV/cm).
Separate high and low frequency filters permit bandwidth reduction, which improves the
signal-to-noise ratio. Connectors are provided on the back of the PB-3 for using the
Bio-Amplifier with other instruments, such as various signal-recording devices. The Bio-Amplifier section of the PB-3 is available separately as Catalog No. 7092-631.
