Approximately 50% of patients with GERD-like symptoms have no evidence of acid reflux on endoscopy and 24 h pH testing. New research shows that multichannel intraluminal impedance (MII) pH testing ...

Today’s electronic equipment must be designed to, first, operate in the electromagnetic (EM) environment it is to be employed in, and second, ensure that the EM fields generated by the system do not ...

Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...
