Interferential Therapy Machines
DIGIMED® 301
DIGIMED® 301 is a computerised interferential therapy equipment that combines IFT, Russian Current and TENS in a single mains-powered unit. With dual carrier frequency (2000 Hz / 4000 Hz), 55 condition-wise pre-set protocols, 30 user-settable memory slots and DSP-based circuitry for output accuracy, it is built for physiotherapy clinics, hospitals and rehabilitation centres that need a reliable multi-modality electrotherapy system with straightforward 5-key operation.

Advanced IFT Control & Clinical Performance
DIGIMED® 301 brings computerised control to three electrotherapy modalities — IFT, Russian Current and TENS — with DSP-driven output accuracy, 55 pre-set protocols and a future-upgradeable hardware platform designed for long-term clinical use.
3-Modality Electrotherapy Output
Combines Interferential Therapy (four-pole classic, four-pole vector 90°, four-pole vector 45°, two-pole pre-modulated), Russian Current (2500 Hz carrier, 50–250 Hz burst, constant/surge) and TENS (2–250 Hz, continuous/burst modes) into a single clinical unit — covering both medium-frequency and low-frequency electrotherapy requirements.
Dual Carrier Frequency — 2000 Hz / 4000 Hz
Operates at both 2000 Hz and 4000 Hz carrier frequencies with a base frequency range of 1–150 Hz (1 Hz step) and sweep frequency of 1–150 Hz (1 Hz step). Sweep modulation programs include 1/1S, 1/5, 1/5S and 6/6S for varied stimulation patterns during IFT sessions.
55 Pre-Set Condition-Wise Protocols
Pre-programmed with 55 treatment protocols organised by clinical condition. Each protocol auto-configures the appropriate modality, frequency, sweep and timing parameters. Physiotherapists can also save custom settings to 30 user memory locations and recall them by patient name for repeat sessions.
DSP-Based Circuitry — 100% Output Accuracy
Digital Signal Processing (DSP) circuitry ensures the set output parameters are delivered with 100% accuracy across all three modalities. This eliminates analogue drift and provides consistent, repeatable output current (0–100 mA) session after session.
Large Graphic LCD & 5-Key Operation
A large graphic LCD display (128×64 resolution) shows all active parameters — current type, therapy mode, frequency, sweep, intensity and timer. Five soft-touch keys handle all navigation and parameter adjustments, keeping the interface simple for daily clinical use.
Future-Upgradeable & Safety Certified
Hardware platform supports future software upgrades without physical component changes — extending the useful life of the equipment as new protocols or modalities become available. Includes an advanced patient safety system with automatic cable and electrode fault detection. Certified to IEC 60601-1 (Class 1, Type BF). Also designed for veterinary care applications.
