Description

The TR72A WiFi & Bluetooth Temperature Humidity Data Logger

The TR72A allows you to measure and record temperature from 0 to 55°C and humidity from 10 to 95% RH.

The LCD screen allows the simultaneous display of either the current values of two channels, the highest and lowest values of channel 1, or the highest and lowest values of channel 2. The ALM icon on the LCD alerts the user of the occurrence of an alarm.

Use the wireless LAN feature to auto-upload data to the cloud for any time, anywhere access, and get warning notices. Connect to a PC with a USB cable to download recorded data and make setting changes.

It is perfect for not only homes and offices but for warehouse and storage facilities.

Special Features

The TR72A uses a wireless LAN access point to auto-upload recorded data and warning notifications to our free cloud-based “T&D WebStorage Service“. To make settings from and download data via USB to a PC, use our Windows software “TR7 for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

The “T&D Thermo” mobile app that enables data viewing and settings from smartphones and tablets via Bluetooth communication will provide support for the TR72A in late 2021.
