24 vs 32 vs 64 Channel EEG: Which Should Your Hospital Buy?
"How many channels do we need?" is the first question every buyer asks. The answer depends on your caseload, your staff and your plans for growth.
The quick comparison
| Feature | 24 Channel | 32 Channel | 64 Channel |
|---|---|---|---|
| Standard 10-20 coverage | Yes | Yes | Yes, plus dense extended montage |
| Extra polygraphic channels | A few | More | Many |
| Video EEG | Optional on some models | Commonly paired | Usually included |
| Typical users | Clinics, ICU, OPD | Multispecialty hospitals | Epilepsy centres, research |
| Price (incl. GST) | ~₹1.12 lakh | ~₹1.40–1.68 lakh | ~₹4.20 lakh |
24 channel EEG: the routine workhorse
The international 10-20 system uses 19 scalp electrodes plus references. A 24 channel amplifier records the full montage with a few channels to spare for ECG, EOG or respiration. Portable 24 channel units like the NEUROCOMPACT weigh well under a kilogram, which makes them ideal for ICU and bedside recordings.
Choose 24 channel if you mainly run routine and sleep-deprived EEGs, need portability, or are setting up your first EEG service.
32 channel EEG: flexible and upgradeable
Thirty-two channels let you add polygraphic channels (ECG, EMG, respiration, eye movements) for sleep and paediatric work, along with extra electrodes such as T1/T2. Systems like the NEUROMAX NMX-32 can be expanded to 64 channels and paired with synchronised video.
Choose 32 channel if you are a multispecialty hospital, expect volume to grow, or plan to start video EEG within a year or two.
64 channel EEG: high-density and research
High-density recordings improve spatial resolution for source localisation, which matters in epilepsy surgery work-ups and research. The NEUROMAX NMX-64 pairs 16-bit acquisition with dual-monitor video and a night-vision camera for long-term monitoring.
Choose 64 channel if you run an epilepsy monitoring unit, a neurosurgery programme or a research lab.
Other factors that matter more than channel count
- Technician training. Good electrode application beats extra channels every time.
- Recording duration. Longer recordings capture more events, so video EEG with long-term monitoring often adds more value than extra channels.
- Software. Look for flexible montages, filters, event marking and standard export.
- Service. Make sure local engineers can reach you quickly.
Our recommendation
Most hospitals in East and Northeast India start with 24 or 32 channels and add video when epilepsy volumes grow. Talk to our team for a free assessment, or read our EEG machine price guide.

Frequently Asked Questions
Is 24 channel EEG enough for epilepsy diagnosis?
For routine diagnosis, yes. Complex cases and pre-surgical work-ups benefit from video and higher channel counts.
Can I upgrade later?
Modular systems such as the NEUROMAX NMX-32 can be expanded to 64 channels.
Does more channels mean better diagnosis?
Not by itself. Technician skill, electrode quality and recording duration matter just as much.
