Good morning –
We've found the HOBO dataloggers by Onset Computers to be very affordable and accurate and generally recommend them; they are easy to set up and maintain and I've always had good tech support from the Onset folks. Recently we've deployed both the UX-100 series 2.5% loggers ($125) and the MX-series T/RH wireless loggers ($135) and have received good data with them.
For collections risk analysis we also recommend that our clients add a subscription to IPI's eClimate Notebook® software for analysis and review.
Happy to answer any other questions either on or off list.
