*1: 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.
*2: Battery life varies depending upon the frequency of communication, 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.
*3: For installation, it is necessary to have Administrator ( Computer Administrator ) rights.
*4: If you are using Windows 8, please note that our software is designed to be used in "Desktop" mode only.
*5: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.

Automatic Data Upload via LAN
Equipped with a wired LAN (TR-7nw), the TR-7wf/nw series data loggerscan automatically upload recorded data to “T&D WebStorage Service” at the set interval. “T&D
WebStorage Service” is a cloud service provided by T&D free of charge. It enables the viewing of uploaded data on your PC or mobile device anytime, anywhere.
One and a Half Years of Operation with just Two Batteries
Battery-powered operation means the device can be placed anywhere without the need for AC power.
Depending on the settings, the TR-7wf/nw series can be used continuously for up to 1.5 years before its
batteries need to be replaced.
Get Temperature and Humidity in a Wider Range with Greater Accuracy
TR-72nw-H comes with a high precision temperature/humidity sensor. Features
include a humidity measurement accuracy of ±2.5%, as well as the wide range measurement of
temperature from -30 to 80 °C and humidity from 0 to 99%RH.
Large Logging Capacity: 8000 Data Sets
One data set consists of readings for all channels in that type of unit. If set at a recording interval of 60
minutes, it gives the user one year's worth of measurements.
Easy Operation via Front Buttons
It is possible to start and stop recording, change recording interval, and make the auto-upload setting by
using buttons on the device.
