Case Study - Asia Society Museum

The Asia Society Museum, located at the Society's headquarters in New York, hosts groundbreaking exhibitions of traditional and contemporary Asian and Asian-American art. The museum’s storage areas comprise two dedicated rooms requiring different humidity levels, one for works of paper, ivory, wood, and lacquer and the other for bronzes as well as collections of porcelain and stone. The museum used to use recording drum hygrothermographs, however, when suppliers stopped producing paper charts for these units, the team needed to find a suitable replacement to continue monitoring humidity and temperature.

After researching several options, the museum team selected Lascar's EL-WIFI-TH wireless data logger and after a successful trial they were installed in all four galleries, the two storage rooms, and in exhibition display cases containing both permanent collection and loan objects to monitor ambient and display case conditions.

“The reporting is easy, and because we can export to PDFs, we can print, file, and refer back to these reports at a later date. Some of our lenders not only want a report of the current readings but will ask to see the numbers in the previous year for that time period. The loggers enable us to meet these requests.” Clare McGowan, Senior Registrar and Collections Manager, Asia Society

Case Study - Lake County Discovery Museum

Curt Teich was a pioneer both in the printing industry and as a promoter of color postcards. Between 1898 and 1978 his company printed more than 1 million different postcard designs, and a copy of every one was carefully archived. This incredible collection can now be found at the Lake County Discovery Museum, 35 miles northwest of Chicago. The postcards were mostly manufactured as cheap and disposable items and so ensuring their long term survival means closely controlling both temperature and humidity. For a time the museum used analogue hygro-thermometers but these proved unreliable and so they switched to Lascar's digital USB data loggers instead.

“We needed something simple and so when these Lascar loggers arrived, I turned them over to our Archives Assistant. I was amazed when he came back into my office two minutes later saying he’d already programmed them. The loggers are now situated throughout the Archives building, taking hourly samples of temperature and humidity which we download once a month to look at the graphed data. They are so simple – just stick them into the USB port to program – and they’re ready to go.” Christine Pyle, Historical Resources Manager, Lake County Discovery Museum

Calibration Assures Accuracy

All EasyLog data loggers can be provided with a calibration certificate

They are calibrated using apparatus traceable to national or international standards

Each logger purposefully tested at the temperatures you will be using it in
