A sensor with no more limits

FREEEMG 1000 H2O is the evolution of BTS technology for EMG analysis specially designed for water measurement.

Thanks to a special protective gel, the electronic components included in the case are completely waterproof, and allow the immersion of the probe in water up to a depth of 3 meters (IP68 classification).


Water sports, indoor training and post-injury recovery


neuromotor and orthopedic

When to use it

Clinical/rehabilitative field:

  • Neuromotor aquatic rehabilitation
  • Post-injury aquatic rehabilitation


Sport field:

  • Analysis of the motor gesture in all water sports, in indoor training
  • Application in sports with sweat resistance

As simple as drinking a glass of water

The subject preparation requires only a few minutes and the special probe technology allows a completely safe immersion in water.

The probe is applied with pre-gelled electrodes and the signal is acquired on the onboard memory of the probe without any loss of the acquired data.
