Agreed. If you set them to read too often, say every 10 minutes, they you have to download them more often, otherwise the early data gets erased. Unless you have a serious problem somewhere, hourly should be plenty of time, then you might only have to download like once a month!

We set our loggers in the building to read hourly, largely because that gives us a good window of time before we need to read out the loggers. We have found that hourly readings are plenty frequent enough to document the kinds of temp/rH fluctuations that we see. For loggers that are going in travel crates we set the readings much more frequently, since the exposure is greater.

Subject: [MUSEUM-L] Recording thermohydrograph
Hello all,
I recently acquired several digital thermohydrographs. They seem to be incredibly flexible with their recording settings, and I was wondering how often should I set my loggers to record. For example , is recording the temperature/humidity hourly overkill or not enough? Also how often should I be reading these things out?
Many thanks for any advice you could give me
Cheers
Mark
