Human Physiology and Research
Digitimer has a long history of designing and manufacturing high output electronic stimulators and amplifiers that are completely safe for use by researchers and clinicians for a variety of applications. Many have also been designed and FDA certified for use on patients undergoing surgery. Digitimer amplifiers are low mains noise solutions for accurate recordings of signals such as EMG/EEG.
High output, low mains noise, and human safety are Digitimer hallmarks.
