The TR-71wf is a temperature WiFi data logger, while the TR-72wf and TR-72wf-H are temperature /humidity
WiFi logger. In addition to the basic features of T&D's standard data loggers, such as battery operation and USB communication function*1, the TR-71wf/72wf supports communication with mobile devices and can be used without a PC. An optional USB communication cable (sold separately) is required. To carry out the auto uploading of recorded data to T&D WebStorage Service, it is necessary to have Internet access via a wireless LAN and a T&D WebStorage Service User ID. These products are applicable for temperature and humidity management in Hospitals, Museums, and Temperature Controlled Warehouses. By using T&D WebStorage Service*2, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere.
