Mettler Sys*Stim 228 Portable Two-Channel Neuromuscular Stimulator
Description
The Mettler Sys*Stim 228 is a professional-grade portable neuromuscular stimulator built for clinical versatility and ease of use. Designed for clinicians who need a reliable, multi-waveform device, it delivers four discrete waveforms - Interferential, Premodulated, Medium Frequency (Russian Stim), and Biphasic - covering everything from pain management to functional rehabilitation. Its intuitive controls make setup fast, while adjustable phase duration, frequency, and a full suite of treatment modes give practitioners the flexibility to tailor every session. Weighing just 4.9 pounds with a built-in carry handle, the Sys*Stim 228 is genuinely portable and ready to go wherever treatment is needed. Whether treating a single patient across two body areas or two patients simultaneously with independent timer control, this unit rises to the demands of a busy clinical environment.
Key Features
- Four Discrete Waveforms: Interferential (IFC), Premodulated, Medium Frequency (Russian Stim), and Biphasic - covering pain management and functional rehab needs.
- Two Independent Channels with Dual-Timer Mode: Treat two separate patients or two body areas simultaneously, each with independent protocol control.
- Adjustable Treatment Parameters: Clinicians can set on/off times, pulse width, frequency, and frequency modulation for precise, patient-specific treatment.

The Sys*Stim 228 is trusted by physical therapists, chiropractors, and sports medicine clinicians who need a dependable, full-featured stimulator without the bulk of a stationary device.

The dual-timer capability is a genuine productivity asset in busy clinics, letting you keep two treatment protocols running concurrently. Built by Mettler Electronics, a company with decades of experience in therapeutic technology, the 228 is engineered for years of consistent clinical performance. Its portable form factor means it works just as well on the move as it does on a treatment cart, making it an ideal choice for practitioners who split time between locations.

FAQ
Can I treat two patients at the same time with the Sys*Stim 228?
Yes. The Sys*Stim 228 features two independent channels with separate timer control, allowing you to treat two patients simultaneously or apply two separate protocols to two different body areas on the same patient at the same time.
What waveforms does the Sys*Stim 228 offer?
The 228 offers four discrete waveforms: Interferential (IFC), Premodulated, Medium Frequency (Russian Stim), and Biphasic. This makes it suitable for both pain management and functional rehabilitation applications.
Can the Sys*Stim 228 be used with a Mettler ultrasound unit for combination therapy?
Yes. The unit includes a pin-to-banana adapter that allows you to run stimulation from the Sys*Stim 228 through a compatible Mettler ultrasound (such as the Sonicator 740) for simultaneous combination therapy.
What electrodes work best with the Sys*Stim 228?
Mettler recommends using their EZ Trodes or V Trodes electrodes for optimal performance. Higher-quality electrodes generally deliver a better treatment experience and more consistent conductivity.
Is the Sys*Stim 228 portable enough for home visits or travel?
Absolutely. At just 4.9 pounds with a built-in carry handle, the 228 was designed with portability in mind. A purpose-built carrying bag is also available as an accessory for clinicians who transport the unit frequently.
Is this device appropriate for pain management?
Yes. The Sys*Stim 228 was designed with pain management as a primary application. It offers both Interferential (IFC) and Premodulated waveforms - two of the most widely used modalities for pain relief - while also supporting a broader range of rehabilitative treatments.
