$2,685.00 NZD

Replaces M200MA model.



– Infection treatments, Iontophoresis, Cancer Apoptosis, DC Cranial Device –

The M250MA model SIS machine is capable of all M250 model functions, and can be used for infection treatments and all other possible applications of the M250 model.

The M250MA has additional electronics and circuit calibration to increase the maximum Output Current to 2.0 milliamperes (mA), intended for specialist clinical or research applications, including:

  • Liquid medication iontophoresis (transcutaneous drug delivery).
  • Small area surface infection treatment via small surface area contact probe (electrode).
  • Transcranial direct current stimulation (tDCS), a form of cranial electrical stimulation (CES).
  • Cellular apoptosis stimulation.
  • Constant current generator for laboratory use.
