The FE132 Bio Amplfier is a fully isolated, high performance differential amplifier for use with PowerlLab. Filter settings optimized for the measurement of a wide variety of biological signals including EEG, ECG and EMG, from a single unit. The FE132 comes equipped with an output jack for headphones or powered speakers, MLA2540 Shielded Bio Amp Cable and MLA2505 Shielded Lead Wires. The FE132 Bio Amp is a single channel, galvanically-isolated device (certified safe for human connection, BF rated).

  • Full electrical isolation from power line (mains) circuitry to guarantee subject safety
  • A low-noise, high gain differential amplifier specifically designed for biological signal measurements
  • Software-controlled low-pass, high-pass and notch filters to remove unwanted signal frequencies
  • Audio output for use with EMG or EEG signals and similar

Applications:

EEG, ECG and EMG, sensory nerve action potentials (SNAP), visual evoked response (VER), cortical evoked potentials and smooth muscle studies.
