CR6 Datalogger (Campbell Scientific)

De CR6 datalogger (meet- en regeldatalogger) biedt snelle communicatie, lage stroomvereisten, ingebouwde USB, compact formaat en hoge analoge ingangsnauwkeurigheid en resolutie. De datalogger maakt gebruik van universele (U) -aansluitingen om een ​​verbinding met vrijwel elk type sensor mogelijk te maken – analoog, digitaal of slim. Deze multifunctionele datalogger is ook in staat om statische Vibrating Wire metingen uit te voeren. De CR6 datalogger is optioneel leverbaar met geïntegreerde radio-opties (CR6-RF433: 868 MHz).
