摘要

Appts. comprises a holder to receive sample containers each having a noble metal electrode contacting the sample and a body of different metal forming a second electrode insulated from the first. The first electrode and container body present contact surfaces externally to engage contacts on the holder. - Noble metal contacts are connected to separate terminals of a multiplexing recorder system and the body contacts are connected to a common lead and to a common terminal of the system. Each container pref. has an aluminium body and a gold-plated pin projecting through the upwardly domed bottom of the container. A printed circuit board is pref. secured to the underside of the holder and is connected to a microprocessor.
