Biopac Epoch Differential transmitters

Epoch differential transmitters enable wireless recording of two different biopotentials with their own reference.

Biopac Epoch Differential transmitters

Part #: EPOCH-P-DIF-SEN, EPOCH-M-DIF-SEN, EPOCH-R-DIF-SEN

Epoch differential transmitters enable wireless recording of two different biopotentials with their own reference.

Record long-term EEG+EEG, EEG+ECG, EEG+EMG, or ECG+EMG.

Transmitters amplify biopotentials and wirelessly transmit data to a receiver tray placed under each animal cage for continuous wireless recording of rats, mice, or pups. There is no crosswalk between cages, unlike other types of implantable transmitters that use RF.

Transmitters ship deactivated—activate with EPOCH-ACTI when ready to start recording.

Choose transmitter size/battery life:

  • 2-week (P10) - EPOCH-P-DIF-SEN
  • 2-month - EPOCH-M-DIF-SEN
  • 6-month - EPOCH-R-DIF-SEN
