CAS Data Loggers is pleased to announce the new TR4A Series from T&D. They represent the next generation of the popular TR4 family of low-cost, compact, Bluetooth wireless data loggers. While keeping all of the features of the previous TR4 series, the TR4A series adds support for Bluetooth Low Energy (BLE) 4.2 wireless communication with a mobile device along with the new TR43A temperature humidity model to go along with the other temperature-only models.
The T&D Thermo mobile application available for iOS and Android allows for set-up, monitoring, and data retrieval using a smartphone or tablet. Data downloaded from the loggers with the T&D Thermo app can be uploaded to the free WebStorage Service for analysis using a standard web browser. There is also the TR4 report application for iOS/Android that allows the generation of PDF reports for customizable time periods right from your mobile device.
