Digitimer DS3 Isolated Constant Current Stimulator
Brief pulses of electricity are used in various biomedical research applications as a stimulus to excite nerve or muscle fibers. Several factors need to be considered when choosing the right stimulator.
The DS3 provides a precise Constant Current stimulus (up to 32mA) controllable in Pulse Duration and Amplitude and as with the DS2A this output comes from self-contained batteries.
The DS3 also features a “clamp” or discharge circuit which discharges the output between stimuli, preventing a charge build up on the preparation. In other constant current devices this charge build up can lead to a loss of stimulus. The DS3 can be triggered by an external device such as our new DG2A Train/Delay Generator.
NOTE: This stimulator is NOT approved for use on human subjects.
