TENS Machines
INDOTENS 4ch
INDOTENS® 4ch is a microcontroller-based 4-channel TENS machine with 9 pre-set programs plus manual mode, frequency sweep and a wider pulse width range of 20–400 µsec. Operating at 1–250 Hz (1 Hz steps) with continuous and pulsed output, a 5-digit 7-segment LED display and mains-only power, it is designed as a straightforward, lightweight (1.25 kg) 4-channel TENS unit for clinics that need multi-channel output with essential pre-set and manual control.
4 Independent Channels
9 Pre-Sets + Manual Mode
20–400 µsec Pulse Width
Frequency Sweep
1.25 kg Lightweight
IEC 60601-1 Certified
Essential 4-Channel TENS, Wider Pulse Width
INDOTENS® 4ch delivers 4-channel TENS with 9 pre-sets, manual mode, frequency sweep and the widest pulse width range (20–400 µsec) in the HMS TENS lineup — in the lightest 4-channel form factor at 1.25 kg.
4 Independent TENS Channels
Four independent output channels for simultaneous multi-area TENS application. All channels share the same frequency and pulse width settings but have independent intensity control, allowing different stimulation levels per channel based on electrode placement and patient tolerance.
9 Pre-Set Programs + Manual Mode
P-0 provides full manual control over all TENS parameters. P-1 through P-9 offer pre-set programs that auto-configure frequency, pulse width and output mode for quick setup. Soft-touch keys handle program selection and parameter navigation.
20–400 µsec Pulse Width Range
The widest pulse width range in the HMS TENS lineup — 20 to 400 microseconds. This extended range gives physiotherapists more options for adjusting pulse characteristics compared to the 20–250 µsec range on the DIGITENS® 4s, particularly for applications that benefit from wider pulse durations.
1–250 Hz with Frequency Sweep
TENS frequency adjustable from 1 to 250 Hz in 1 Hz steps. Frequency sweep mode automatically modulates the stimulation frequency during treatment. Continuous and pulsed output modes available. Treatment timer up to 90 minutes.
5-Digit 7-Segment LED Display
A 5-digit 7-segment display shows key output parameters clearly. While simpler than the DIGITENS® 4s graphic LCD, the LED display provides reliable, high-visibility readout of active settings in all lighting conditions.
1.25 kg — Lightest 4-Channel TENS
At 1.25 kg and 24 × 28 × 9.8 cm in an ABS cabinet, INDOTENS® 4ch is the lightest 4-channel TENS unit in the HMS range. Mains-powered (90–270V AC). Certified to IEC 60601-1 (Class I, Type BF). Also designed for veterinary care. Manufactured by HMS Medical Systems.
