Electronic instrumentation can use an assortment of reed relays. Examples of these instruments would be data acquisition testing, electrometers, printers, medical cauterizing generators, medical test systems, multimeters, RF switching and transmitting, scanners and multiplexers. Various instruments are used to detect and analyze very small voltages and currents, reed relays with very low capacitance across the contacts are ideally suited to handle these signals without any loss in signal strength. Ninety-seven percent of hospitals now use electronic scalpels which not only cut tissue, but cauterize the cut as well. They use up to 10 A at frequencies up to 2 MHz. This critical technology uses reed relays exclusively.
