Monitoring the environment

Until now we have relied on a rather clunky but lovely thermohygrograph to keep a track on the temperature and humidity in the museum.

One box of tricks, with specially purchased and expensive graph paper wrapped round a drum, has been kept in one room of the museum. It was large, but I have to say we rather liked it.

But now that old system has become redundant. Our ‘reward’ for loaning items to the Wiltshire in 100 objects exhibition has been four modern environmental monitors. We can now keep a record in each of our display areas. It’ll take up much less potential display chase and be cheaper to run. That’s not just win/win. It’s win/win/win!

It is thanks to these little beauties.

These devices operate for almost any period of time. We can set them, by attaching to the USB port of a computer (with the appropriate and downloadable software). At the moment we have chosen to allow them to run for a full year but of course we can interrupt this at any time. When we choose, we can connect them to the computer again and the data is uploaded and can then be presented in graph form.

Here we see a graph from a few days of trial for the upstairs device.

These are very useful and welcome additions to help us ensure we maintain a suitable environment for our artefacts.
