At present we use TinyTags. These record the temperature and RH at intervals which you can specify, I have ours set to every 30 minutes. It is necessary to download the data physically from the units, I have the software installed on a laptop, and just go round and connect to each unit every month and download the data. They seem to be fairly accurate, they arrive calibrated and can be recalibrated, but this has to be done by the manufacturer. The data you get is a simple graph showing the readings, and you can view it as a table of data. It is possible to copy and paste the data from this table into Excel or any other spreadsheet, and obviously from there you can extract any data you require. I have a spreadsheet into which I plug the data which gives me the highest and lowest temperature and RH for each day, and also the number and percentage of days on which the readings are outside those recommended for archive storage.
