Success Stories

"The HOBO MX1101 is an ideal solution for us to protect such an important historical artifact as the Magna Carta. It’s great that I can check the current conditions at a glance, and have the ability to access historical data without interfering with the exhibit."
Emily Naish
Emily Naish, Archivist at Salisbury Cathedral
"The time reduction for downloading the MX2001 logger in our wells is significant, since most are 25 to 500 feet deep. The Bluetooth capability eliminates the need to remove the logger from the well and threat of tangled cable."
