Description

When nerve pain and muscle discomfort interrupt your day, switching between multiple devices only adds frustration. This 4 channel TENS unit combo puts four therapies — TENS, EMS, Interferential (IF), and Russian stimulation — into a single portable electrotherapy device you can use at home, in the clinic, or on the go. With separate intensity controls for each of the four channels, you can fine-tune your session to exactly the level you need. Four channels also let you cover large areas like the entire back, or work multiple treatment sites at the same time, so you spend less time cycling through sessions.

You stay in control from start to finish. The large LCD screen keeps your settings visible at a glance, and intensity adjusts with the press of a button. Two independent treatment timers run from 1 to 60 minutes or continuously, counting down automatically so you never have to watch the clock. Adjustable ramp time eases each cycle in and out for a more comfortable session. A built-in compliance meter stores up to 60 operation records, making it simple to track your usage or share it with your physician or therapist. Everything you need comes in the box — carrying case, four sets of lead wires, eight reusable electrodes, batteries, and an AC adapter — so you're ready to begin the day it arrives.

Features
  • Four Therapies in One Device — Combines TENS, EMS, Interferential, and Russian stimulation in a single portable electrotherapy device, replacing multiple units and simplifying your pain management and muscle re-education routine.
  • Independent 4 Channel Control — Separate intensity controls on each channel let you treat large areas like the entire back, or multiple treatment sites at once, with settings customized per channel.
  • Dual Treatment Timers — Two adjustable timers run 1 to 60 minutes or continuously and count down automatically, so each session ends on schedule without monitoring.
  • Built-In Compliance Meter — Stores up to 60 operation records covering 999 hours of use, giving you a reliable usage log to review with your physician or therapist.
  • Complete Kit, Ready to Use — Arrives with carrying case, four lead wire sets, eight reusable electrodes, batteries, and AC adapter, so this 4 channel TENS unit combo works right out of the box.
