Description

The TandD TR71A WiFi & Bluetooth Temperature Data Logger

The TR71A is a temperature logger with two available sensor connections and can measure from -60 to 155℃. The wide range of optional sensors provides increased measurement flexibility.

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.

The software application used with the TR71A has a “Vaccine Mode”, which meets or exceeds CDC requirements for VFC, and is useful for monitoring and recording vaccine temperatures. TR71A is useful not only in research labs and hospitals, but also in homes, offices, and other industries.

Special Features

The TR71A 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 TR71A in late 2021.
