Can we help you?

Capable of measuring, displaying and recording temperature and humidity.

The TR-72wb uses a wireless LAN access point to auto-upload recorded data and warning notifications to our free cloud-based “T&D WebStorage Service” or your Windows PC running the "T&D Data Server" software. Use our mobile app “T&D Thermo” to check data from your smartphone or tablet and use Bluetooth communication to make settings and download recorded data. To make settings from and download data via USB to a PC, use our Windows software “TR-7wb/nw for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.
