Chattanooga Primera TENS/NMES Complete With HAN Waveform

The Primera TENS/NMES Complete with Chattanooga's distinctive HAN Waveform offers a unique dispense and disperse mode of stimulation which modulates between low (2 Hz) and high (70 Hz) frequencies. It also features an extensive range of programs configured for the user's specific clinical needs. There are 8 TENS programs used for temporary pain relief and 6 NMES programs to stimulate and improve muscle performance. The complete package includes: a PRIMERA Unit, Carrying Case, Battery, Leadwires, Electrodes, Electrode Positioning Back Belt and User's Manual.          

Key Features & Benefits:

• 2-in-1 TENS & NMES Therapy: Combines Transcutaneous Electrical Nerve Stimulation (TENS) and Neuromuscular Electrical Stimulation (NMES) in one portable unit.
• 14 Preset Programs: Includes 8 TENS programs and 6 NMES programs, helping simplify treatment setup without requiring users to manually build stimulation parameters.
• Unique HAN TENS Waveform: Alternates low-frequency 2 Hz stimulation with higher-frequency 70 Hz stimulation in repeating phases for a distinctive TENS treatment option.
• Dual-Channel Output: Two individually isolated channels allow stimulation through multiple electrodes and independent intensity adjustment for each channel.
• Up to 80 mA Output: Both TENS and NMES modes provide adjustable stimulation from 0-80 mA into a 500-ohm load.
• Multiple TENS Modes: Preset options include Continuous, Burst, Modulated, and HAN TENS waveforms.
• Built-In Safety Features: Open-electrode detection automatically resets output current to zero when an open circuit is detected, while the LCD provides a low-battery warning.
• Portable 9V Operation: Compact, lightweight design operates from a replaceable 9-volt alkaline battery, making the unit convenient for home or on-the-go use.

Common Uses:

TENS Pain Relief

The Primera TENS programs are intended for temporary relief of pain associated with sore and aching muscles of the lower back, arms, and legs resulting from strain associated with normal, non-commercial household activities.

NMES Muscle Stimulation

The NMES programs are designed to stimulate healthy muscles in order to facilitate and improve muscle performance. Six preset NMES programs provide different stimulation rates and work/rest cycles for varied muscle-stimulation needs.

Why Choose The Chattanooga Primera?

Primera is a strong choice for users who want more versatility than a basic TENS unit without moving to a larger clinical electrotherapy system. Instead of purchasing separate pain-relief and muscle-stimulation devices, Primera combines TENS and NMES with 14 preset programs in one compact platform. Its dual-channel design, dedicated HAN waveform, straightforward controls, back electrode-positioning belt, replaceable battery, and complete accessory package make it especially convenient for ongoing home electrotherapy.
