Automatic Data Upload to Cloud
By using wireless LAN (wf) and wired LAN (nw), the logger automatically uploads the recorded data to T&D WebStorage Service. The uploaded data can be accessed from multiple computers, smartphones and tablets.
T&D WebStorage Service is a free cloud-based service provided by T&D Corporation. Internet access is required to use the service.
Easy USB Communication
USB connection to PC allows device setup, data download, graph view and data list view.
The necessary software can be downloaded free of charge.
Direct Communication with Mobile Devices
By using our specialized mobile app, you can directly log on to a TR-7wf in AP mode and download recorded data to your smartphone or tablet, or make device settings for the data logger. Direct communication may not work properly with some Android devices. This feature requires button operation on the TR7wfunit for each communication access, therefore cannot be operated remotely.
Sending Warning Report Mails
Upon receiving warning information from the target device T&D WebStorage Service will send out a warning e-mail to the set recipients.
1.5 Years of Operation with just Two Batteries
With just two AA batteries the logger can be used for about 1.5 years.
* Actual battery life is not guaranteed.
Large Logging Capacity: 8000 Data Sets
It is possible to record up to 8000 sets of data measurements in two separate channels. That means at a recording interval of 60 minutes you can keep on recording for one year before reaching capacity.
Easy Operation via Front Buttons
It is possible to start and stop recording, change recording interval, and make the auto-upload setting from the buttons on the face of the logger.
