GM320TP GM350TP
Pre-Program and C/MW adjustable TENS with two Independent channels
The GEM-STIM Digital TENS Series is a professional dual-channel stimulator designed for pain management applications. It is available for OEM manufacturing and private label branding to meet diverse market requirements.
The new two-independent-channel stimulator. You can use P2 for channel 1 and use P6 for channel 2 at the same time for different treatment areas. It is good for different pain and areas.
The preprogrammed mode is easy operated by user. Especially, there are two adjustable modes: one is C mode, and the other one is MW mode, both with rate and width adjustable.
