This category contains sensors intended to be for general purpose use, meaning they have standard 1.5 mm safety socket connectors and signal output ranges suitable for use with most bioamplifiers.  If you are not sure a given sensor is compatible with your biosignal acquisition system, contact us.  If you won one of the products we sell, then we should be able to help.  If you have a different make/model but you know its technical inner workings well enough to answer questions about the input connector type / pinout, input voltage range, frequency response and other parameters, then we can probably help you settle on a sensor that will work.  If you do not know your own hardware that well, then contact your hardware provider to get answers to these questions before asking us for assistance.  We will need this information to be able to help you.
