Description

The TR-72wf-S WiFi Temperature Humidity Data Logger

The TR-72wf-S WiFi Temperature Humidity Data Logger is a high precision two-channel model with an external thermistor sensor and a measuring range of -25 to 70°C and a humidity range of 0 to 99%RH. In addition to the standard features such as battery operation and USB communication (through optional cable, sold separately), the TR-72wf-S supports communication with mobile devices. By using T&D’s WebStorage Service, users can access stored data anytime from the cloud.

Access to Recorded Data

By using a wireless LAN, data is automatically uploaded to the WebStorage Service (registration required). The service can be used with mobile devices such as smartphones and tablets allowing users to monitor current readings, alerts and downloading of data. The ThermoWeb application must be downloaded and installed on any mobile device. Data can also be downloaded to a PC with a USB communication cable (sold separately).

  • *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.
