CAS DataLoggers and T&D have product launched the new TR-71wf/72wf Series Wireless Temperature and Humidity Data Loggers. These two-channel environmental monitors have an auto-communication function which automatically uploads all recorded data from the loggers over wireless LAN to T&D’s free cloud service. Now users can view data anytime, anywhere on a mobile device or PC. These wireless data loggers are ideal for temperature and humidity management in hospitals, museums, warehouses, and for server room environmental monitoring, HVAC performance testing of humidity and heat control, and many more applications.

The new temperature loggers use external sensors to record on two channels in either °C or °F, and also offer a combination logger which uses a channel for temperature and a second channel recording the percentage of relative humidity. The temperature logger measures from -40° to 230°F (-40° to 110°C) using the supplied sensor and monitors an even wider range using an optional sensor. The combination logger measures from 32° to 131°F (0° to 55°C) and 10 to 95%RH. The company also offers a high-accuracy model of the combo logger with an expanded monitoring range of -22 to 176°F (-30° to 80°C) and 0 to 99%RH.
