Den kan brukes for strømmer opp til ±3 A og en samsvarsspenning på opptil ± 28 V. Med en inngangsimpedans på mer enn 10 TΩ || 5 pF, er potensiostaten egnet for et bredt spekter av elektrokjemiske oppgaver.
Potensiostater
Zahner potensiostater er designet for å gi høyeste ytelsesnivå i elektrokjemiske eksperimenter. I mange tiår har de vist seg å være presise og allsidige enheter for alle slags elektrokjemiske applikasjoner. Disse fleksible potensiostatene kan tilpasses de individuelle behovene til brukerne for bruk innen ethvert felt innen elektrokjemi eller fotoelektrokjemi.
ZENNIUM PRO er en modulær high-end potensiostat / galvanostat inkludert en frekvensresponsanalysator (FRA). ZENNIUM PRO potensiostaten tilbyr 32-bits DC-oppløsning og 24-bits AC-oppløsning over 12 forskjellige strømområder, noe som gjør at den kan utføre presise og nøyaktige målinger. Mulig utvidelse med opptil 5 parallelle impedanskanaler og ekstra spor for tilleggskort gjør ZENNIUM PRO til en allsidig, kraftig og presis potensiostat for bruk innen alle felt innen elektrokjemi.
