SANTA FE, N.M. - Nov. 24, 2021 - PRLog -- T&D Corporation, the only manufacturer of wireless and stand-alone data loggers providing free and unlimited cloud data storage, today announced that its popular TR4 Report companion app for T&D's TR4 Bluetooth® Series Data Loggers is now available for Android. The application allows the user to easily create, download and share reports on a mobile device to determine whether the proper temperature was maintained during transportation, storage, and so on. Android users can download the TR4 Report app on the Google Play store.

"Our TR4 Series Data Loggers are widely popular due to the ability to quickly connect to a user's mobile device via Bluetooth to review data," said Stephen Knuth, president, TandD US, LLC. "These loggers are often used by customers measuring temperature during transit and the TR4 Report app expands their capabilities by allowing them to quickly generate, download and share reports on the go. We're proud to make this technology available to our customers on Android."

TR4 Report connects to the TR4 Series Data Loggers via Bluetooth and allows the user to view reports on their mobile devices. The data is displayed in graphical form in a .pdf file and shows the user high and low temperature readings during a specified time as well as whether or not alarms have been triggered by the temperature of the storage environment going outside a specified range. The graphs can be downloaded and shared via email or printed out.

The TR4 Series Data Loggers have become especially popular as a device to measure vaccines with cold-storage requirements, such as the COVID-19 vaccine, in transit and in storage due to their compatibility with PT100 and thermocouple sensors. These sensors are used to measure temperatures as low as -199 °C. The release of the TR4 Report app allows these users to quickly generate reports to prove that vaccines are kept at correct temperatures and avoid irreparable damage.
