I have available a few extra Onset Hobo UX100-003 T/RH data loggers with visible digital display from a lot I bought from a private party. These are the latest version logger from Onset that sells for $89. Each comes with a 3-point (10, 20, 30 deg C) NIST temperature Certification of Accuracy, an additional cost of $140 each from Onset, for a total cost of $229. I call their condition like new since I can not verify they are new because I did not purchase them from an authorized dealer. However, the only previous launches were for the certification process by Onset. As a courtesy to the museum profession, I can sell them for $114, half price, plus postage. This is the same logger I used as the reference for my recent informal evaluation of digital T&RH monitors. I only have a few of these available, so first come, first served.
