TENS Machines
DIGITENS 4s
DIGITENS® 4s is a microcontroller-based 4-channel TENS machine with 20 pre-set programs (15 for TENS applications, 5 for fitness), manual parameter control, frequency sweep, a 128 × 64 graphic LCD display and built-in rechargeable battery with 5 hours backup. Operating at 1–250 Hz (1 Hz steps) with pulse width of 20–250 µsec, continuous and pulsed output modes and individual intensity control per channel, it is designed for clinics, hospitals and sports facilities that need multi-channel TENS capability with both pre-set and manual operation.

Multi-Channel TENS with Programme Flexibility
DIGITENS® 4s combines 4-channel output, 20 pre-set programs, manual parameter control and frequency sweep with a rechargeable battery and graphic LCD — the most feature-complete TENS machine in the HMS range.
4 Independent TENS Channels
Four output channels with individual intensity control and display for each channel. All four channels can operate simultaneously, allowing stimulation of multiple body areas in a single session. Independent intensity adjustment lets physiotherapists set different stimulation levels per channel based on electrode placement and area sensitivity.
20 Pre-Set Programs — 15 TENS + 5 Fitness
Comes loaded with 15 pre-set TENS programs and 5 fitness programs. Each preset auto-configures frequency, pulse width, output mode and timing parameters. Manual mode provides full parameter access for physiotherapists who need custom settings beyond the presets. Programs are selected via soft-touch keys.
1–250 Hz Frequency with Sweep
TENS frequency adjustable from 1 to 250 Hz in 1 Hz steps with pulse width of 20–250 microseconds. Frequency sweep mode automatically varies the stimulation frequency during treatment. Continuous and pulsed output modes are available. Treatment timer adjustable up to 90 minutes.
128 × 64 Graphic LCD Display
A graphic LCD display (128 × 64 resolution) shows all active TENS parameters — frequency, pulse width, output mode, treatment time and individual intensity output for each of the four channels. Clear parameter visibility helps clinicians monitor and adjust treatment without interruption.
Built-In Rechargeable Battery — 5 Hours Backup
Features a maintenance-free rechargeable battery providing up to 5 hours of continuous operation without mains power. Dual power capability (mains + battery) allows uninterrupted treatment during power outages or portable use outside the clinic. Mains input: 90–270V AC.
1.75 kg ABS Cabinet
Housed in a portable ABS cabinet measuring 23 × 23 × 9.5 cm and weighing 1.75 kg. Microcontroller-based circuitry manages all output and safety functions. Certified to IEC 60601-1 (Class I, Type BF). Also designed for veterinary care. Manufactured by HMS Medical Systems.
