Fluke 712B RTD kalibraatorid
Fluke 712B RTD kalibraator pakub väga täpset, lihtsat ja lihtsat ühefunktsionaalset RTD temperatuuri kalibreerimist.
Fluke 712B RTD-kalibraator on käeshoitav akutoitega seade, mis mõõdab ja saadab erinevaid RTD-tüüpe ja -takistusi. See sisaldab ka isoleeritud kanalit 4-20 mA mõõtmiseks, samal ajal kui see annab temperatuuri signaali. See pakub konfigureeritavaid 0% ja 100% allikasätteid 25% lineaarsuse kiireks kontrollimiseks. See pakub ka lineaarse rambi ja 25% astmelise automaatse rambi funktsiooni, mis põhineb 0% ja 100% seadistustel.
Lisaks sellele on kaks sisendit, hõlpsasti vaadeldav taustavalgustusega ekraan ning võimalus salvestada seadistused väljalülitamisel, et neid saaks hõlpsasti taaskäivitada, mistõttu on 712B ideaalne katsevahend temperatuuri kalibreerimise spetsialistidele, kes soovivad väga täpset, hõlpsasti kasutatavat, ühe funktsiooniga RTD temperatuuri kalibraatorit.
Muud kasulikud omadused:
Kaks sisendit ja taustavalgustusega ekraan mõõtmiste hõlpsaks tõlgendamiseks.
Mäletab väljalülitatud seaded, et testid oleksid hõlpsasti taaskäivitatavad, kui seade on uuesti sisse lülitatud.
Pakub lineaarset rampi ja 25% sammuga automaatset rampi, mis põhineb 0% ja 100% seadistustel.
Pakub ühe- ja kaheaastaseid spetsifikatsioone ja jälgitavat kalibreerimise sertifitseerimist.
