De SL7000 dataloggers hebben een zeer flexibele combinatie van input van een enkele temperatuur tot 4 universele ingangen die elk afzonderlijk kunnen worden geconfigureerd om een combinatie van de volgende typen invoer accepteren:
RTD / Pt100
Thermokoppel (type J, K, T, R, S, B, N) (geïsoleerd tip)
-mA (4-20mA 4/20mA)
-volt
-mV
-thermistors
-Slidewire
-cu
-Ni
Onderaan de pagina zijn de bestelcodes te vinden.
Alle SL7000 dataloggers hebben een interne temperatuursensor en een digitale ingang die kan worden gebruikt als een trigger voor een logboekregistratie te starten of als pulsteller voor interfacing met debietmeters of andere pulsegevende sensoren.
Een optionele interne relatieve vochtigheid sensor met een nauwkeurigheid ± 2% is beschikbaar op alle eenheden alsmede een optionele externe temperatuur en relatieve vochtigheid sensor. Dit geeft een totaal van 9 kanalen - interne temperatuur, interne pulsteller, interne relatieve luchtvochtigheid, buitentemperatuur en relatieve vochtigheid en twee of vier universele ingangen.
