GM320PP GM350PP
GM350PP Pre-Programmed TENS with 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-channels 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.

PS. The mode content:
Burst: Cycle Bursts, 2Bursts/sec, 9pulses/Burst, 100Hz.
Continuous mode: Continuous output
Modulated Width. Pulse width is automatically varied in an interval of 6 seconds. The modulation range of pulse width is from 140μs to 260μs, then returns to 140μs in 6 sec cycle time.
Rate modulation. MR consists of alternating pulse rates from 3 Hz to 100 Hz, then returns to 3 Hz in a 6-sec cycle time.
Waveform: Asymmetrical Bi-phasic square pulse.
Voltage: 0-110 Volt (Open Circuit).
Max charge per pulse: 21 microcoulombs
Power Source: 9-Volt Battery.
Dimensions: 122mm(H) ×65mm(W) ×25mm(T).
Weight: 140grams (battery included).
All electrical specifications are ±10% at a 500Ω load.
