The TR-72wb is a temperature/humidity logger and it can be purchased in a high precision version, the TR-72wf-H.  The TR-71wf is a temperature data logger that can monitor two temperature zones, while 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. 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.


*1: An optional USB communication cable (sold separately) is required.
*2: 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.

  • *1 : With the TR-71wf, it is also possible to measure temperature with the internal sensor. However, the measurement range is restricted to the operating environment for the whole device.
  • *2 : When used in environments where temperature and humidity are over the values of 50 °C 75 %, 60 °C 50 %, 70 °C 35 %, and 80 °C 25 %, sensor hysteresis may fluctuate by values greater than ±1.5 %RH. Under certain circumstances, it may take some time to return to normal measurement capability.
  • *3 : The WPS feature is not available when WEP(64bit/128bit) or WPA-PSK(TKIP) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK(AES) or disable wireless security.
  • *4 : Optional USB Mini-B Cable US-15C is required for USB communication.
  • *5 : Battery life varies depending upon the frequency of communication, wireless LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.

Easy ordering

Easy ordering, And very prompt service. We ordered the same units in the past and have used him extensively. We are very happy with the high-quality

Great Bread Thermometer

I love the big dial which makes it easy to read, unlike the ones they sell in the stores, which have small dials. I could not find a thermometer made just for yeast and dough. I am glad that I came across your website.

V21-WTH

This gift was well received, especially since the recipient picked it out. Got it up and running in time for the good storm (very windy today). We live on the northern coast of California and usually have at least 7 mph winds on a slow day. Today we are having 20-30 mph winds, love the new weather station!!

On time and professional service
