Channels: Dual-channel (supports two pads or pairs simultaneously)
Output Modes: Multiple preset therapy modes + fully adjustable manual mode
Frequency Range: 2Hz – 150Hz (depending on mode selected)
Pulse Width: Adjustable up to 260µs
Intensity Levels: 20–30 levels (fine control for sensitive or deep stimulation)
Timer Settings: 15, 30, 45, and 60-minute selectable treatment times
Waveform: Symmetrical biphasic square wave
Duty Cycles: Continuous, burst, and modulation patterns
Battery Type: Two AA batteries (standard or rechargeable)
Dimensions: Approx. 4.5" x 2.5" x 1"
Display: Digital LCD screen with mode, timer, and intensity indicators
Classification: FDA-approved Class II medical device
The DA1812 delivers targeted electrical pulses to block pain signals and stimulate endorphin release—this means relief without medication, side effects, or dependency risks.
With adjustable intensity, frequency, pulse width, and modes, users can tailor treatment exactly to their comfort and pain level.
Treat two body areas at once or use two pads per channel for a wider treatment zone—ideal for back, shoulders, or legs.
This lightweight battery operated TENS unit runs on AA batteries, allowing pain relief anywhere—home, office, travel, or therapy sessions.
Easy-to-read display makes selecting modes and adjusting settings simple, even for first-time users.
Includes burst, modulation, and continuous modes—meaning you can switch between relaxing muscle pulses or strong therapeutic stimulation.
As an FDA Class II medical device, the DA1812 is safe, non-invasive, and designed for everyday pain management.
Therapists appreciate its precision; home users love its simplicity. Perfect for chronic pain conditions, post-exercise soreness, or rehabilitation.
The Digital TENS AA Unit – DA1812 is ideal for treating:
Relieves soreness from workouts, tension, strains, and everyday fatigue.
Helps reduce stiffness and discomfort from arthritis, tendonitis, and sprains.
Effective for chronic lower-back pain, cervical strain, and sciatica.
Reduces swelling and enhances circulation in targeted areas.
Loosens tight muscles and prevents recurring spasms.
Provides relief for neuropathy, pinched nerves, and radiating pain.
TENS uses electrical pulses to interrupt pain signals traveling to the brain. By stimulating sensory nerves, it:
Reduces pain perception
Increases blood flow
Triggers endorphin release
Relaxes tight muscles
This makes the DA1812 a versatile tens therapy device for chronic and acute conditions.
