I have seen this one (sorry in French, but there is some graphs) :
Enregistreur USB longue durée température et humidité - T°, %RH et point de rosée pour Diagnostic de Performance Energétique (DPE) ou autre - 64.50EUR- achats éconologiques
It saves up to 16000 points with temperature and humidity. You configure the time between the records from 2s to 24h.
Velleman sells in US but I don't know if this recorder is sold in US.
