Weekly Charts Sling Psychrometer

In 1990 I was appointed as Conservation Liaison. Among my duties were the maintenance, repair and distribution of information captured by the existing hygrothermographs.

High cost of upkeep includes the purchase of


• Require staff commitment to regularly change the charts and calibrate the units.

• Expense of both equipment and staff time involved.

Thermohygrometer Kit

Difficulties with the maintenance of hygrothermographs:


• After 2 years of struggling with staff maintenance issues, I began the process of researching the availability of electronic sensors to replace the hygrothermographs.

• Based on operating costs we were able to purchase electronic dataloggers. We chose the ACR Dataloggers supplied by the Cascade Group, Oyster Bay, NY. Website: http://www.temprh.com/

• A laptop used for downloading information in the field, then it is transferred to a desktop, charts are edited for uniformity and then distributed to corresponding curators and facilities personnel.
