Making Physiology Happen


iWire-BIO4 4-Channel Biopotential iWire Recording Module

iWorx has developed a proprietary Serial Interface technology called iWire. iWire devices enable unparalleled expansion of your laboratory recording equipment by simply plugging in an iWire compatible device. Need to add 4 EMG channels to your protocol? No problem, simply plug in an IX-BIO4 iWire device. A traditional data recorder would require 4 additional recording channels to accomplish this.

In addition to measuring Bio-Potentials, each channel is also capable of measuring temperature using the TM-BIO temperature sensor.
