DSI’s First Dual Module Device
Telemetric recording of physiologic data coupled with automated sleep-wake scoring software, facilitates the understanding of the neurobiological regulation of sleep homeostasis, circadian rhythms, stress and arousal, conditioning, and emotion and cognition. With our new 4ET transmitter, you can easily collect 4 channels of any combination of EEG, EMG, EOG or ECG data plus temperature, around-the-clock. The 4ET transmitter is DSI’s first dual module device, enabling long-term studies through a minor subcutaneous telemetry module replacement to extend battery life.

Accommodates Paired Housing
Another key benefit of the 4ET transmitter is that animals may be monitored while pair-housed — promoting more natural sleep and behavior patterns. DSI’s complete line of telemetry allows wireless monitoring of freely moving animals.
