WebStorage Service

Free Online Service for Cloud Data Storage

It’s never been so easy to share your recorded data via the Internet! T&D’s free WebStorage Service is perfect for processing and managing data recorded in remote places or for allowing several people to view the same recorded data at their convenience. Users can check the current conditions of data loggers such as battery level and radio signal strength between the Base Unit and Remote Unit. Recorded data can be transmitted to the WebStorage Service from any compatible Tamp;&D product. Data storage capacity is 20MB.

Additionally, the data transmitted to T&D WebStorage Service can be accessed via your browser from anywhere, anytime, as long as an internet connection is available. Mobile device apps are also available for devices running iOS and Android.
