 High Performance Four-Channel Amplifier and Signal Conditioner

 

model440The Brownlee Precision Model 440 incorporates four channels of sophisticated amplifier and filter circuitry in a friendly, easy to use instrument. Each channel consists of a high gain/low noise voltage amplifier, an 8-pole Bessel lowpass filter, a highpass filter, a line notch filter, and an output offset control. A control knob sets the amplifier parameters and the values are displayed on a bright LED alphanumeric readout. Download Model 440 Datasheet Here.
